FlexWebListPlugin 
  Description 
This is a replacement for Foswiki's standard 
WEBLIST variable.
It is extended to improve the display of hierarchical web structures,
a feature added to later wikis and adds more flexibility when used in
WikiApplications. The FLEXWEBLIST can be used for example 
to generate a hierarchical navigatio scheme or a nested sitemap.
  Syntax 
%FLEXWEBLIST{...}%
This tag iterates over all specified webs and all of their subwebs recursively
while using the specified format strings to produce the output. 
Parameters: 
-  webs: a list of webs to be displayed and/or      "public" - a list of all non-hidden webs,      "webtemplate" - a list of all template webs;      "publiccurrent" - a list of all non-hidden webs including the current one;     (defaults to "public")
-  format: format string to render one item      (defaults to "$web ")
-  header: format string prepended to the output result
-  footer: format string appended to the result; if the list     of webs is empty neither header nor footer are added.
-  separator: text to be put between webs; can benonefor no separators
-  subformat: format string to be used to format subwebs     (defaults toformat)
-  subheader: format string preceding the output of any subweb     (defaults toheader)
-  subfooter: format string following the output of any subweb;     subheader and subfooter are only added if the list of subwebs of the      current web is not empty     (defaults tofooter)
-  subseparator: text to be put between subwebs; can benonefor no separators     (defaults toseparator)
-  subwebs: regular expression that subwebs must match to be listed; this     can also benone,all,onlyto suppress subwebs, show all or only dispay explicitly     mentioned subwebs (default isall)
-  selection: selected items in the list of webs
-  marker: text for$markerif the item maches the selection      (see pseudo variables below)
-  markerformat: format string used instead of (sub)format string     for selected items
-  exclude: regular expression of items excluded from the output
-  include: regular expressions of items that must match in order to be     included in the output
-  ignorecase: on/off; if switched onincludeandexcludechecks are done case-insensitive (defaults to off)
-  adminwebs: a regular expression of webs that are considered to be only relevant for WikiAdmins and are hiddend to non-admin users. In general it is recommended to     hide webs by restricting access rights to it. There are however cases when you want to hide a web     but still use it although the user is not aware of it. Best example is     and Application web holding WikiApplications. Users are using those     applications but should not be bothered with their implementation.
-  map: list ofkey=valuepairs to map the name of a web to a different value     (e.g. map="System=Documentation,Main=Home" will expand the variable$nameas "Documentation" instead of System     and as "Home" instead "Main")
Parameters default to the emtpy string if not mentioned otherwise. Note, that some
of them although similar to WEBLIST have different default values. 
Pseudo-variables: Each of the above format strings (format, header, footer, 
subformat, subheader, subfooter and markerformat) may contain special variables
that are replaced with a current value: 
-  $web: the full name of the web, e.g.Main/Foo/Bar
-  $qname: the full name of the web in quotes, e.g."Main/Foo/Bar"(deprecated)
-  $name: the name of the web without the leading parent webs, e.g.Bar
-  $origname: the original name of the web despite any name mapping
-  $parent: the name of the parent web of a sub web or the empty string if there's none
-  $marker: marker text (see above) if the current item is selected, empty otherwise
-  $depth: level of embedding of a subweb; main level web have depth 0 etc.
-  $nrsubwebs: number of subwebs a current web has
-  $indent: expands to three spaces for each level a web is embeded; main level     webs get three spaces, subwebs on first level six spaces and so on.
-  $indent(string): same as$indentbut usingstringinstead of three spaces
-  $n: replaced with a newline char (\n)
-  $percnt: replaced with a percent char (%)
-  $dollar: replaced with a dollar char ($)
-  $nop: removed from the format string before expanding common foswiki variables
-  $url: link to homepage of web
-  $sitemapuseto: content of the SITEMAPUSETO preference of the web
-  $sitemapwhat: content of the SITEMAPWAT preference
-  $color: content of the WEBBGCOLOR preference
