[[features.conf]]
Feature configuration file (`features.conf`)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This file contains various compile-time configuration settings, which you can
adjust below. You can fine-tune the ELinks binary to include really only what
you want it to. It acts as a front-end to the configure script in the sense
that it is possible to control any features in this file by passing arguments
to the configure script. In fact any arguments given to the script will
overrule the values set in this file.

There are still some things which are to be adjusted only directly through the
configure script arguments though, so check ./configure \--help out as well!

All dependency checking is done by the configure script so even though a
feature is enabled here it is possible that it will be disabled at compile
time if the dependencies are not met. Check the features.log file generated
by the configure script to make sure.




Notes for users
^^^^^^^^^^^^^^^


All features that can be controlled using this file are already set to their
default values. The syntax used is hopefully familiar to most people.

'#' chars start a comment that runs until the end of the line.

The features are controlled by setting the various CONFIG_<FEATURE> variables
to either 'yes' or 'no' depending on whether it should be enabled or disabled.
So in order to disable bookmark support a line in this file should say:

	CONFIG_BOOKMARKS=no

It is also possible to simply comment out the line in order to disable it.
Therefore, if the default doesn't suit you, you can either comment it out or
set it to the value you desire.



[[CONFIG-BOOKMARKS]]
Bookmarks (`CONFIG_BOOKMARKS`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


ELinks has built-in hierarchic bookmarks support. Open the bookmarks manager
by pressing 's'. When bookmarks are enabled, also support for the internal
ELinks bookmarks format is always compiled in.

This is a favourite target for disabling in various embedded applications.
It all depends on your requirements.

Also read the ``The Ultimate Bookmarks Guide'' in doc/bookmarks.txt

*Default:*  enabled

[[CONFIG-XBEL-BOOKMARKS]]
XBEL Bookmarks (`CONFIG_XBEL_BOOKMARKS`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


ELinks also supports universal XML bookmarks format called XBEL, also
supported by e.g. Galeon, various "always-have-my-bookmarks" websites and
number of universal bookmark converters.

Frequently, you know you will not need it, then you can of course happily
forcibly remove support for it and save few bytes.

*Default:*  enabled if libexpat is found and bookmarks are enabled

[[CONFIG-COOKIES]]
Cookies (`CONFIG_COOKIES`)
^^^^^^^^^^^^^^^^^^^^^^^^^^


Support for HTTP cookies --- a data token which the server sends the client
once and then the client sends it back along each request to the server.  This
mechanism is crucial e.g. for keeping HTTP sessions (you "log in" to a site,
and from then on the site recognizes you usually because of the cookie), but
also for various banner systems, remembering values filled to various forms,
and so on. You can further tune the ELinks behaviour at runtime (whether to
accept/send cookies, ask for confirmation when accepting a cookie etc).

This functionality is usually quite important and you should not disable it
unless you really know what are you doing.

*Default:*  enabled

[[CONFIG-FORMHIST]]
Form History (`CONFIG_FORMHIST`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


The famous Competing Browser has that annoying thing which pops up when you
submit a form, offering to remember it and pre-fill it the next time. And yes,
ELinks can do that too! You will still need to also enable this manually at
document.browse.forms.show_formhist.

Many people find it extremely annoying (including pasky), however some others
consider it extremely handy and will sacrifice almost anything to get it. It
will not do any harm to have this compiled-in as long as you will leave it
turned off (which is also the default configuration).

*Default:*  enabled

[[CONFIG-GLOBHIST]]
Global History (`CONFIG_GLOBHIST`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


This device records each and every page you visit (to a configurable limit).
You can browse through this history in the history manager (press 'h').  Do
not confuse this with the "session history", recording history of your
browsing in the frame of one session (session history is the thing you move
through when pressing 'back' and 'unback' or which you see in the
File::History menu).

Global history does not care about the order you visited the pages in, it just
records that you visited it, when did you do that and the title of the page.
Then, you can see when did you visit a link last time (and what was the title
of the target document at that time), links can be coloured as visited etc.

If you disable this feature, you will not lose any crucial functionality, just
some relatively minor convenience features, which can nevertheless prove
sometimes very practical.

*Default:*  enabled


MIME
^^^^


ELinks uses a MIME system for determining the content type of documents and
configuring programs for external handling. By default the option system can
be used to configure how media types are handled. More info about how to set
up the MIME handling using the option system can be found in the doc/mime.html
file.

Below are listed some additional ways to do it.



[[CONFIG-MAILCAP]]
Mailcap (`CONFIG_MAILCAP`)
^^^^^^^^^^^^^^^^^^^^^^^^^^


Mailcap files describe what program - on the local system - can be used to
handle a media type. The file format is defined in RFC 1524 and more info
including examples can be found in the doc/mailcap.html file.

This is very useful especially for clean interoperability with other
MIME-aware applications and fitting nicely into the UNIX system, where this is
the standard way of specifying MIME handlers. If you are not interested in
that, you can still use the internal MIME associations system, though.

*Default:*  enabled

[[CONFIG-MIMETYPES]]
Mimetypes File (`CONFIG_MIMETYPES`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Mimetypes file can be used to specify the relation between media types and
file extensions.

Basically same thing applies here as for the mailcap support.

*Default:*  enabled

[[CONFIG-GZIP]]
Gzip and Deflate Decompression (`CONFIG_GZIP`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


This makes ELinks send "Accept-Encoding: deflate, gzip" in HTTP
requests and decompress any documents received in those formats.
It works with local *.gz files as well.

*Default:*  enabled if zlib is installed and new enough

[[CONFIG-BZIP2]]
Bzip2 Decompression (`CONFIG_BZIP2`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


This makes ELinks decompress local *.bz2 files.
Also, ELinks sends "Accept-Encoding: bzip2" in HTTP requests
and decompresses any documents received in that format,
but this encoding has not been registered at
http://www.iana.org/assignments/http-parameters[],
so most servers probably won't use it.

*Default:*  enabled if the library is installed

[[CONFIG-LZMA]]
LZMA Decompression (`CONFIG_LZMA`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


This makes ELinks decompress local *.lzma files.
Also, ELinks sends "Accept-Encoding: lzma" in HTTP requests
and decompresses any documents received in that format,
but this encoding has not been registered at
http://www.iana.org/assignments/http-parameters[],
so most servers probably won't use it.

To use this, first install http://tukaani.org/lzma/[LZMA Utils].
Version 4.32.5 works; 4.42.2alpha also works and understands a
newer LZMA file format.  This version of ELinks does not support
LZMA SDK from 7-Zip.

*Default:*  disabled

[[CONFIG-IPV6]]
IPv6 Protocol Support (`CONFIG_IPV6`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


You know this thing that was designed to obsolete IPv4 but only pasky,
weirdos and projects supported with big funds really use. ;-)

*Default:*  enabled if the system supports it

[[CONFIG-URI-REWRITE]]
URI Rewriting (`CONFIG_URI_REWRITE`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


The goto dialog through which new URIs can be entered is an essential part of
browsing in ELinks. This feature makes the dialog more powerful by making it
possible to extend how entered text is handled through a set of rewrite rules
(see protocol.rewrite options).

There are two types of rules: simple and smart ones.

Simple rewriting rules are basically URI abbreviations, making it possible to
map a word to the full URI. They can also be used for hierarchic navigation to
ease moving from some nested directory to the parent directory or doing other
stuff with the current URI. For example, when you type 'gg' into the goto
dialog, you will be materialized at Google's homepage.

Smart rules can take arguments and therefore enable more advanced rewriting.
The arguments could be search words to google for or a lookup query for a
dictionary. Eg. type 'gg:Petr Baudis king of ELinks cvs'.

This feature is also available in a more powerful form in the Lua and Guile
extensions, so if you plan to or already use those, you won't miss anything by
disabling this feature (besides easier and better integrated configuration).

*Default:*  enabled

[[CONFIG-BITTORRENT]]
BitTorrent Protocol Support (`CONFIG_BITTORRENT`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


The BitTorrent protocol is a protocol for distributing files in a peer-to-peer
(P2P) manner. It uses the HTTP protocol for communicating with a central
server and a peer-to-peer (P2P) protocol for exchanging file pieces betweens
peer downloaders. The integrity of file pieces downloaded from peers are
checked using cryptographic hashing (SHA1).

Downloads using BitTorrent are started by first downloading a .torrent file
with the MIME type "application/x-bittorrent". The file contains information
which enables ELinks to ask a central server, called a tracker, for
information about other downloading peers and start downloading from and
uploading to them.

At any time, an external handler can always be defined to take precedence of
the internal BitTorrent client and the internal client can always be forced
by prefixing the URI of the .torrent file with "bittorrent:"

NOTE: The BitTorrent support is still experimental.

*Default:*  disabled

[[CONFIG-CGI]]
Local CGI Support (`CONFIG_CGI`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


ELinks can (like w3m or lynx) execute certain executable files stored on the
local disks as CGIs, when you target it on them (through a URI of the 'file'
scheme). ELinks emulates the complete CGI environment, like the program would
be executed by a web server. See the protocol.file.cgi options tree for
detailed runtime configuration.

Some people just write their bookmark management application as Perl CGI
script and then access it from the web browser using this feature, not needing
any web server or so. Therefore, this is a great possible way to extended the
browser capabilities.

Even when you compile this in, you need to enable this yet in the
configuration, and even then only CGI files passing certain user-defined
filters (path-based) will be allowed to be executed (and there are certain
other security barriers in place).

*Default:*  disabled, available if setenv() or putenv() is found

[[CONFIG-DATA]]
Data URI protocol (`CONFIG_DATA`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


The data URI protocol is defined in RFC 2397 and allows inclusion of small
data items as "immediate" data, as if it had been included externally.

A data URL might be used for arbitrary types of data. The URI

	data:,A%20brief%20note

encodes the text/plain string "A brief note", which might be useful in a
footnote link.

*Default:*  enabled

[[CONFIG-FINGER]]
Finger User Information Protocol Support (`CONFIG_FINGER`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


The finger protocol is a simple protocol defined in RFC 1288. The server
return a friendly, human-oriented status report on either the system at the
moment or a particular person in depth such as whether a user is currently
logged-on, e-mail address, full name etc. As well as standard user
information, it displays the contents of ".plan" file in the user's home
directory. Often this file (maintained by the user) contained either useful
information about the user's current activities, or alternatively all manner
of humor.

It is most often implemented on Unix or Unix-like systems however due to
security and privacy reasons it is usually disabled or only allowed locally on
the system.

*Default:*  disabled

[[CONFIG-FSP]]
File Service Protocol (`CONFIG_FSP`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


File Service Protocol (FSP) is a very lightweight UDP based protocol for
transferring files. FSP has many benefits over FTP, mainly for running
anonymous archives. FSP protocol is valuable in all kinds of environments
because it is one of the only TCP/IP protocols that is not aggressive about
bandwidth, while still being sufficiently fault tolerant.

FSP is what anonymous FTP *should* be!

See http://fsp.sourceforge.net/ for more info.

*Default:*  disabled

[[CONFIG-FTP]]
File Transfer Protocol Support (`CONFIG_FTP`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


The File Transfer Protocol (FTP) is a software standard for transferring
computer files between machines with widely different operating systems.

Many sites that run FTP servers enable so-called "anonymous ftp". Under
this arrangement, users do not need an account on the server. By default,
the account name for the anonymous access is 'anonymous'. This account
does not need a password, but users are commonly asked to send their email
addresses as their passwords for authentication (protocol.ftp.anon_passwd),
but there is no verification.

See also http://en.wikipedia.org/wiki/Ftp .

*Default:*  enabled

[[CONFIG-GOPHER]]
Gopher Protocol Support (`CONFIG_GOPHER`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

SFTP
See https://en.wikipedia.org/wiki/SSH_File_Transfer_Protocol .
Requires libcurl.


Gopher is a distributed document search and retrieval network protocol
designed for the Internet in RFC 1436. The need for gopher arose in in the
early days of the hypertext Internet where the number of documents that were
being published in campus and research environments could not easily be
distributed using known protocols like FTP because these documents were stored
not in one place, but in many computers connected to the Internet.

The support works much like local file browsing with directories (aka. menus)
and various file types that can be downloaded and viewed.

It is still very experimental and the CSO phone-book protocol is not
implemented.

*Default:*  disabled

[[CONFIG-NNTP]]
NNTP Protocol Support (`CONFIG_NNTP`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Network news transport protocol support makes it possible to access nntp
and news servers and read postings. It is still very experimental and is
far from being considered a ``news reader''.

It is possible to list news groups on a server, articles in a news group
and retrieve articles by their number or message-id.

*Default:*  disabled

[[CONFIG-SMB]]
SMB Protocol Support (`CONFIG_SMB`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


ELinks supports browsing over the SMB protocol (URI 'smb' scheme),
using the libsmbclient library as back-end.  Therefore, in order to
have this enabled, you will need to install Samba (or at least just
the libsmbclient part, if you can install it separately).

This use of libsmbclient is believed to be immune to the command
injection attacks (CVE-2006-5925, bug 841) from which earlier ELinks
releases (0.9.0 to 0.11.1) suffered.

*Default:*  disabled

[[CONFIG-CSS]]
Cascading Style Sheets (`CONFIG_CSS`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Simplistic CSS support. It is still very much in it's infancy so don't expect
too much. If you have use of background colors enabled more pages will have
the intended background color. Also quite a few additional text attributes are
applied. One example is highlighting of search words on Google's cached pages.

There are options to disable both imported style sheets to minimize network
traffic and whether to use CSS at all. Also a default style sheet can be
defined to control the basic layout in the HTML renderer.

*Default:*  enabled

[[CONFIG-HTML-HIGHLIGHT]]
HTML Highlighting (`CONFIG_HTML_HIGHLIGHT`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Makes it possible to view HTML source with the markup highlighted in colors
configurable using CSS. It also makes values of referencing attributes
accessible like the href="<uri>" attribute in <a> elements.

The HTML highlighting uses components of an experimental DOM implementation
still in progress so enabling this feature will add a considerable amount of
code to the compiled binary. On the other hand it will help to debug what will
hopefully evolve into the next generation document renderer.

*Default:*  disabled, requires that CSS is enabled

[[CONFIG-SCRIPTING-SPIDERMONKEY]]
ECMAScript (JavaScript) Browser Scripting (`CONFIG_SCRIPTING_SPIDERMONKEY`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


By enabling this feature, certain parts of ELinks, such as the goto URL
dialog, may be extended using ECMAScript (aka. JavaScript) scripts. This can
be useful to optimise your usage of ELinks.

For example you can define shortcuts (or abbreviations) for URLs of sites you
often visit by having a goto URL hook expand them. This can also be achieved
with the URI rewrite feature (CONFIG_URI_REWRITE), however it is not as
powerful as doing it with scripting.

*Default:*  enabled if Spidermonkey is found

[[CONFIG-MOUSE]]
Mouse Support (`CONFIG_MOUSE`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


ELinks may be controlled not only by keyboard, but also by mouse to quite some
extent. You can select links, menu items, scroll document, click at buttons
etc, and it should hopefully work. ELinks supports mouse control by GPM, xterm
mouse reporting and TWAIN's twterm mouse reporting.

It is generally nice convenience and doesn't cost too much. However, you can
do everything with keyboard as you can with mouse. Also note that the xterm
mouse reporting takes control over the terminal so that copy and pasting text
from and to ELinks has to be done by holding down the Shift key.

*Default:*  enabled

[[CONFIG-88-COLORS]]
88 Colors in Terminals (`CONFIG_88_COLORS`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Define to add support for using 88 colors in terminals. Note that this
requires a capable terminal emulator, such as:

- Thomas Dickey's XTerm, version 111 or later (check which version you have
with xterm -version) compiled with \--enable-88-color.

- Rxvt, version 2.7.9 or later compiled with \--enable-88-color.

You will still need to enable this at runtime for a given terminal in terminal
options, or set your $TERM variable to xterm-88color - then, ELinks will
automatically configure itself to make use of all the available terminal
features, while still acting sensibly when you happen to run it in an xterm
w/o the 88 colors support.

When enabled, the memory usage is somewhat increased even when running in mono
and 16 colors mode (the memory consumption can be especially remarkable when
rendering very large documents and/or using very large terminals).  However,
when you actually run it in the suitable terminal, it looks really impressive,
I'd say marvelous!

*Default:*  disabled

[[CONFIG-256-COLORS]]
256 Colors in Terminals (`CONFIG_256_COLORS`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Define to add support for using 256 colors in terminals. Note that this
requires a capable terminal emulator, such as:

- Thomas Dickey's XTerm, version 111 or later (check which version you have
with xterm -version) compiled with \--enable-256-color.

- Rxvt, version 2.7.9 or later compiled with \--enable-256-color.

- Recent versions of PuTTY also have some support for 256 colors.

You will still need to enable this at runtime for a given terminal in terminal
options, or set your $TERM variable to xterm-256color - then, ELinks will
automatically configure itself to make use of all the available terminal
features, while still acting sensibly when you happen to run it in an xterm
w/o the 256 colors support.

When enabled, the memory usage is somewhat increased even when running in mono
and 16 colors mode (the memory consumption can be especially remarkable when
rendering very large documents and/or using very large terminals).  However,
when you actually run it in the suitable terminal, it looks really impressive,
I'd say marvelous!

*Default:*  disabled

[[CONFIG-TRUE-COLOR]]
True color (`CONFIG_TRUE_COLOR`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Define to add support for True color. This mode eats a lot of memory.

*Default:*  disabled

[[CONFIG-TERMINFO]]
Terminfo (`CONFIG_TERMINFO`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Whether to use terminfo for output
Unfinished.

Default disabled



[[CONFIG-EXMODE]]
Ex-mode Interface (`CONFIG_EXMODE`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


The ex-mode interface makes a prompt available when pressing ':'. The prompt
can be used for entering actions like ':goto-url' and configuration file
commands.

The code is still very experimental and lacks much work such as tab
completion.

*Default:*  disabled

[[CONFIG-LEDS]]
LEDs (`CONFIG_LEDS`)
^^^^^^^^^^^^^^^^^^^^


These are the tiny LED-like indicators, shown at the bottom-right of the
screen as [-----]. They are used for indication of various states, e.g.
whether you are currently talking through a SSL-secured connection,
what is the current input mode (normal or insert), JavaScript errors etc.

*Default:*  enabled

[[CONFIG-MARKS]]
Document Marks (`CONFIG_MARKS`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Makes it possible to set marks in a document and then later jump to them kind
of like how fragments in URIs work. It is currently only possible to jump to
marks set in the current document.

*Default:*  enabled

[[CONFIG-DEBUG]]
Debug mode (`CONFIG_DEBUG`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^


Assertions are evaluated and will core dump on failure. Some extra sanity
checks are done, and some errors will cause core dump instead of just a
message. Internal memory leak detection is activated (memory usage will grow),
and every allocation/reallocation/free operations will be slower due to extra
tests. Lists sanity checks are enabled, so list operations are slower. Hot-key
debugging is enabled, it highlights redundant hot-keys in a menu.

This option should be _always_ used by beta testers and developers, it helps
to detect many issues. Binary packages maintainers should not use this option
in normal situation.

*Default:*  disabled

[[CONFIG-FASTMEM]]
Fast mode (`CONFIG_FASTMEM`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^


This option provides a way to generate a faster and smaller binary of a
_stable_ version of ELinks. Please do not use it with unstable releases
(unless memory footprint, performance and/or binary size are major issues for
you).

It disables all assertion tests and sanity checks effectively reducing safety.
It disables internal memory allocation routines, directly calling libc
functions (so it's much faster, but memory allocation issues and memory leaks
will be not detected). It defines fmem_alloc(), and fmem_free() to be in fact
alloca() and nothing, providing much faster allocations in routines where they
are used

*Default:*  disabled

[[CONFIG-OWN-LIBC]]
Own C library functions (`CONFIG_OWN_LIBC`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Enable this to use the various C library stub functions that is part of the
portability layer instead of those available in the C library on the system.

It will make the binary slightly bigger and should only be used for testing
the portability layer.

*Default:*  disabled

[[CONFIG-SMALL]]
Small binary (`CONFIG_SMALL`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Reduces the size of the binary but also disables a few memory consuming
optimizations to make the program much lighter when running.

Part of the size reduction is due to various help text not being compiled in
which will affect usability. Also the disabled optimization will make ELinks
run slower.

See doc/small.txt for more information about how to reduce the size of ELinks.

*Default:*  disabled

[[CONFIG-UTF8]]
Unicode UTF-8 support (`CONFIG_UTF8`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


By enabling this option you get better Unicode support. At present only some
parts of ELinks are influenced with this. It includes DOM, plain, HTML
renderer and user interface. Beside normal Unicode characters there is
support for double-width characters (like Japanese, etc.).

Some features of Unicode are not handled at all. Combining characters is
most visible absence.
Some features are partially supported. Like line breaking between
double-width characters. There is no other detection for determining when to
break or not.
Character conversions are still incomplete for ECMAScript strings (bug 805),
local file names, and IRIs (RFC 3987).

*Default:*  enabled

[[CONFIG-BACKTRACE]]
Back-trace Printing (`CONFIG_BACKTRACE`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Once upon a time, a disaster happens and ELinks crashes. That is a very sad
event and it would be very nice to have some means how to diagnose it. In the
crash handler, ELinks prints out various helpful things, however the truly
important information is _where_ did it crash. Usually, users do not have gdb
installed and can't provide a back-trace. However, ELinks can print a
back-trace on its own, if the system supports it (currently, it is implemented
only for glibc). It is not always accurate, it is useless when the ELinks
binary is stripped and it still misses a lot of important information, but it
can be sometimes still an indispensable help for the developers.

You should keep this, unless you will strip your ELinks binary anyway, you
know you are not going to report back any failures and you care about each
single wasted bit.

*Default:*  enabled if the libc supports it (only glibc)

[[CONFIG-NO-ROOT-EXEC]]
Disable Root User (`CONFIG_NO_ROOT_EXEC`)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


Browsers are scary monsters used for traveling around in an even more scary
world where people indifferently throw garbage files at you and threaten your
perfect world. Altho' ELinks is a small monster compared to most browsers, it
can still bite your head off and some might consider running it as the root
user extremely dangerous. To prevent such usage simply enable this feature.

*Default:*  disabled
