" History:
" 1.0   2001-04-26
"		First release for vim5 under the name thlnk.vim
" 1.1   2002-05-07
"		As plugin for vim6 with heavily revised documentation and homepage
" 1.2   2002-06-14
"		Two bug fixes, better error messages, largely enhanced documentation
" 1.2.1 2002-06-15
"		Bug fix. Better 'ff' setting for distribution files
" --- Renamed plugin from Thlnk to Utl ---
" 2.0	2005-03-22
"		Configurable scheme and media type handlers, syntax
"		highlighting, naked URL support, #tn as default, heuristic
"		support and other new features. See ../doc/utl_usr.txt#utl-changes
" 3.0a  ALPHA 2008-07-31
"		New :  Generic media type handler, Mail protocol, Copy Link/
"		Filename support, Foot-References [], Transparent editing of
"		share files, Tracing, Enhanced scheme handler interface,

" `Utl_extractUrlByPattern' - Extracts embedded URLs from 'linestr':
" Extracts URL from given string 'linestr' (if any) at position 'icurs' (first
" character in linestr is 0). When there is no URL or icurs does not hit the
" URL (i.e. 'URL is not under cursor') returns '<undef>'. Note, that there can
" be more than one URL in linestr. Linestr may contain newlines (i.e. supports
" multiline URLs).
"
" 'pat' argument:
" Embedded URL means, that the URL is surrounded by some tag or characters
" to allow for safe parsing, for instance '<url:'...'>'. This regexp pattern
" has to specify a group \(...\) by which defines the URL.
" Example : '<url:\([^<]\{-}\)>'. If an empty pattern '' is given, default
" patterns apply (see code below).
"
" Examples:
"   :echo s:Utl_extractUrlByPattern('Two Urls <URL:/foo/bar> in this <URL:/f/b> line', 35, '')
"   returns `/f/b'
"
"   :echo s:Utl_extractUrlByPattern('Two Urls <URL:/foo/bar> in this <URL:/f/b> line', 28, '')
"   returns `<undef>'
"
"   :echo s:Utl_extractUrlByPattern('Another embedding here <foo bar>', 27, '')
"   returns `foo bar'
"	
" Details:
" - The URL embedding (or if embedding at all) depends on the context: HTML
"   has different embedding than a txt file.
" - Non HTML embeddings are of the following form: <URL:...>, <LNK:...> or
"   <...>
" - Returns `<undef>' if `no link under cursor'. (Note that cannot cause
"   problems because `<' is not a valid URI character)
" - Empty Urls are legal, e.g. <URL:>
" - `Under cursor' is like with vim's gf-command: icurs may also point to
"   whitespace before the cursor. (Also pointing to the embedding characters
"   is valid.)

"id=Utl_processFragmentText-----------------------------------------------------
" Description:
" Position cursor in current buffer according `fragment', modified by
" `fragMode' which can have values 'abs' or 'rel'.
"
" - arg `fragment' can be:
"   tn=string	    - searches  string  beginning at start position forward.
"		      The naked fragment (without a `xx=' as prefix defaults
"		      to tn=).
"   tp=string	    - searches  string  beginning at start position backward.
"   line=number	    - move cursor  number  lines from start position. Number
"		      can be positive or negative. If `fragMode' is 'abs'
"		      -1 denotes the last line, -2 the before last line etc.
"   r=identifier    - (IdReference) search for  id=identifier\>  starting from
"		      begin of buffer. `fragMode' is ignored.
"
" - arg `fragMode' modifies the start position. Can have the values:
"   'abs' = absolute: Cursor is set to begin or end of document, depending on
"	    fragment, then position starting from there.
"	    Start position for tn=, line=nnn, line=+nnn r= is begin of buffer.
"	    Start position for tp=, line=-nnn is end of buffer.
"   'rel' = relative: Start positioning the cursor from current position.
"
" Details: 
" - `fragment' will be URI-Unescaped before processing (e.g. 'tn=A%3aB' ->
"   'tn=A:B')
" - Interpretation of `fragment' depends on the filetype. But currently,
"   the only non generic treatment is for HTML references.
" - `Fragment' can be '<undef>' or '' (empty).
" - If `rel' position the cursor to begin or end of line prior to actual
"   search: a target string in the same line will not be found.
