-=head1 NAME
-
-Pod::Html - module to convert pod files to HTML
-
-=head1 SYNOPSIS
-
-    use Pod::Html;
-    pod2html([options]);
-
-=head1 DESCRIPTION
-
-Converts files from pod format (see L<perlpod>) to HTML format.  It
-can automatically generate indexes and cross-references, and it keeps
-a cache of things it knows how to cross-reference.
-
-=head1 FUNCTIONS
-
-=head2 pod2html
-
-    pod2html("pod2html",
-             "--podpath=lib:ext:pod:vms",
-             "--podroot=/usr/src/perl",
-             "--htmlroot=/perl/nmanual",
-             "--libpods=perlfunc:perlguts:perlvar:perlrun:perlop",
-             "--recurse",
-             "--infile=foo.pod",
-             "--outfile=/perl/nmanual/foo.html");
-
-pod2html takes the following arguments:
-
-=over 4
-
-=item backlink
-
-    --backlink="Back to Top"
-
-Adds "Back to Top" links in front of every C<head1> heading (except for
-the first).  By default, no backlinks are generated.
-
-=item cachedir
-
-    --cachedir=name
-
-Creates the item and directory caches in the given directory.
-
-=item css
-
-    --css=stylesheet
-
-Specify the URL of a cascading style sheet.  Also disables all HTML/CSS
-C<style> attributes that are output by default (to avoid conflicts).
-
-=item flush
-
-    --flush
-
-Flushes the item and directory caches.
-
-=item header
-
-    --header
-    --noheader
-
-Creates header and footer blocks containing the text of the C<NAME>
-section.  By default, no headers are generated.
-
-=item help
-
-    --help
-
-Displays the usage message.
-
-=item hiddendirs
-
-    --hiddendirs
-    --nohiddendirs
-
-Include hidden directories in the search for POD's in podpath if recurse
-is set.
-The default is not to traverse any directory whose name begins with C<.>.
-See L</"podpath"> and L</"recurse">.
-
-[This option is for backward compatibility only.
-It's hard to imagine that one would usefully create a module with a
-name component beginning with C<.>.]
-
-=item htmldir
-
-    --htmldir=name
-
-Sets the directory in which the resulting HTML file is placed.  This
-is used to generate relative links to other files. Not passing this
-causes all links to be absolute, since this is the value that tells
-Pod::Html the root of the documentation tree.
-
-=item htmlroot
-
-    --htmlroot=name
-
-Sets the base URL for the HTML files.  When cross-references are made,
-the HTML root is prepended to the URL.
-
-=item index
-
-    --index
-    --noindex
-
-Generate an index at the top of the HTML file.  This is the default
-behaviour.
-
-=item infile
-
-    --infile=name
-
-Specify the pod file to convert.  Input is taken from STDIN if no
-infile is specified.
-
-=item libpods
-
-    --libpods=name:...:name
-
-List of page names (eg, "perlfunc") which contain linkable C<=item>s.
-
-=item netscape
-
-    --netscape
-    --nonetscape
-
-B<Deprecated>, has no effect. For backwards compatibility only.
-
-=item outfile
-
-    --outfile=name
-
-Specify the HTML file to create.  Output goes to STDOUT if no outfile
-is specified.
-
-=item podpath
-
-    --podpath=name:...:name
-
-Specify which subdirectories of the podroot contain pod files whose
-HTML converted forms can be linked to in cross references.
-
-=item podroot
-
-    --podroot=name
-
-Specify the base directory for finding library pods.
-
-=item quiet
-
-    --quiet
-    --noquiet
-
-Don't display I<mostly harmless> warning messages.  These messages
-will be displayed by default.  But this is not the same as C<verbose>
-mode.
-
-=item recurse
-
-    --recurse
-    --norecurse
-
-Recurse into subdirectories specified in podpath (default behaviour).
-
-=item title
-
-    --title=title
-
-Specify the title of the resulting HTML file.
-
-=item verbose
-
-    --verbose
-    --noverbose
-
-Display progress messages.  By default, they won't be displayed.
-
-=back
-
-=head2 htmlify
-
-    htmlify($heading);
-
-Converts a pod section specification to a suitable section specification
-for HTML. Note that we keep spaces and special characters except 
-C<", ?> (Netscape problem) and the hyphen (writer's problem...).
-
-=head2 anchorify
-
-    anchorify(@heading);
-
-Similar to C<htmlify()>, but turns non-alphanumerics into underscores.  Note
-that C<anchorify()> is not exported by default.
-
-=head1 ENVIRONMENT
-
-Uses C<$Config{pod2html}> to setup default options.

-  --backlink     - set text for "back to top" links (default: none).
-  --cachedir     - directory for the item and directory cache files.
-  --css          - stylesheet URL
-  --flush        - flushes the item and directory caches.
-  --[no]header   - produce block header/footer (default is no headers).
-  --help         - prints this message.
-  --hiddendirs   - search hidden directories in podpath
-  --htmldir      - directory for resulting HTML files.
-  --htmlroot     - http-server base directory from which all relative paths
-                   in podpath stem (default is /).
-  --[no]index    - generate an index at the top of the resulting html
-                   (default behaviour).
-  --infile       - filename for the pod to convert (input taken from stdin
-                   by default).
-  --libpods      - colon-separated list of pages to search for =item pod
-                   directives in as targets of C<> and implicit links (empty
-                   by default).  note, these are not filenames, but rather
-                   page names like those that appear in L<> links.
-  --outfile      - filename for the resulting html file (output sent to
-                   stdout by default).
-  --podpath      - colon-separated list of directories containing library
-                   pods (empty by default).
-  --podroot      - filesystem base directory from which all relative paths

-  --[no]quiet    - suppress some benign warning messages (default is off).
-  --[no]recurse  - recurse on those subdirectories listed in podpath
-                   (default behaviour).
-  --title        - title that will appear in resulting html file.

-</p>
-
-=end html
-
-=head4 Callback return values
-
-All server, command and print  callbacks should return one of
-the C<Xchat::EAT_*> constants.
-Timer callbacks can return Xchat::REMOVE to remove
-the timer or Xchat::KEEP to keep it going
-
-=head4 Miscellaneous Hook Related Information
-
-For server hooks, if C<$message> is "RAW LINE" then C<$cb> will be called for
-every IRC message than X-Chat receives.
-
-For command hooks if C<$command> is "" then C<$cb> will be called for
-messages entered by the user that is not a command.
-
-For print hooks besides those events listed in 
-Settings-E<gt>Advanced-E<gt>Text Events, these additional events can be used.

-C<$nick> -  the nick to look for, if this is not given your own nick will be
-            used as default
-

-
-This function is mainly intended to be used as a shortcut for when you need
-to retrieve some information about only one user in a channel. Otherwise it
-is better to use L<get_list|xchat_get_list>.
-If C<$nick> is found a hash reference containing the same keys as those in the
-"users" list of L<get_list|xchat_get_list> is returned otherwise undef is returned.
-Since it relies on L<get_list|xchat_get_list> this function can only be used in a
-channel context.
-
-=head3 C<Xchat::context_info( [$context] )>
-
-=over 3
-
-=item *
-C<$context> -  context returned from L<get_context|xchat_get_context>, L<find_context|xchat_find_context> and L<get_list|xchat_get_list>, this is the context that you want infomation about. If this is omitted, it will default to current context.
-
-=back
-
-This function will return the information normally retrieved with L<get_info|xchat_get_info>, except this is for the context that is passed in. The information will be returned in the form of a hash. The keys of the hash are the C<$id> you would normally supply to L<get_info|xchat_get_info> as well as all the keys that are valid for the items in the "channels" list from L<get_list|xchat_get_list>. Use of this function is more efficient than calling get_list( "channels" ) and searching through the result.

-
-This function will remove bold, color, beep, reset, reverse and underline codes from C<$string>. It will also remove ANSI escape codes which might get used by certain terminal based clients. If it is called in void context C<$string> will be modified otherwise a modified copy of C<$string> is returned.
