" Description:
" This is a (well... more or less) simple script to comment lines in a program.
" Currently supported languages are C, C++, PHP, the vim scripting
" language, python, HTML, Perl, LISP, Tex, Shell, CAOS and others.
" Bugfixes:
" 2.3
" Fixed type 'apacha' -> 'apache' (thanks to Brian Neu)
" Fixed nested comment escapes strings. (thanks to Samuel Ferencik)
" Fixed broken keyboard mappings when wcm was set to <Tab>.
" (thanks to xpatriotx)
" 2.2
" Fixed problem with UseSyntax (thanks to Pieter Naaijkens)
" Fixed typo in ParseCommentsOp (commstr -> commStr).
" Fixed support for ocaml (thanks to Zhang Le)
" 2.1
" Fixed problems with alignement when a line contains tabs
" Fixed (resp. cleaned up) issues with overrideEL (thanks to Steve Hall)
" Fixed problems with javascript detection (thanks to Brian Neu)
" Changed Buffer init to BufWinEnter in order to use the modelines.
" 2.0
" Fixed invalid expression '\'' -> "'" (thanks to Zak Beck)
" Setting AltOpen/AltClose to '' (ie. disabling it) would
" insert '/*' resp. '*/' for character in a line (thanks to Ben Kibbey)
" 1.8
" Backslashes in comment symbols should not be escaped.
" typo (commensSymbol -> commentSymbol) (thanks to Steve Butts)
" typo (== -> =)
" Fixed hardwired '|+'-'+|' pair.
" 1.7
" Lines were not correctly decommentified, when there was whitespace
" at the beginning of the line. (thanks to Xiangjiang Ma)
" Fixed error detecting '*sh' filetypes.
" 1.3
" hlsearch was set unconditionally (thanks to Mary Ellen Foster)
" made function silent (thanks to Mare Ellen Foster)
" Changelog:
" 2.3
" Added support for viki/deplate (thanks to Thomas Link)
" Added support for xslt/xsd/mail (thanks to Stefano Zacchiroli)
" Added callback-functionality to enable extensions without the
" need of modification directly in the script.
" 2.2
" Added possibility to override the modes, in which keybindings are
" defined.
" Keybindings may be defined local to every buffer now.
" If a filetype is unknown, one can turn off the keybindings now.
" 2.1
" Removed any cursor movement. The script should now be free of
" side-effects.
" The script now uses &commentstring to determine the right
" comment strings. Fallback is still the ugly if-thingy.
" Script can now interpret &comments in order to add a middle
" string in blocks.
" Added EnhancedCommentifySet for use by other scripts. (Necessary?)
" Added MultiPartBlocks for languages with multipart-comments.
" Added parsing for comments option if using MultiPartBlocks.
" 2.0
" IMPORTANT: EnhancedCommentify is now licensed under BSD license
" for distribution with Cream! However this shouldn't
" change anything...
" useBlockIndent does no longer depend on respectIndent.
" Added code to cope with 'C' in '&cpo'. (thanks to Luc Hermitte
" for pointing this out!)
" Added EnhCommentifyIdentFrontOnly option.
" All options are now handled on a per buffer basis. So options
" can be overriden for different buffers.
" 1.9
" Filetype is now recognized via regular expressions.
" All known filetypes are (more or less) supported.
" Decomments multipart-block comments.
" Added RespectIndent, AlignRight and synID-guessing.
" Switched to buffer variables.
" 1.8
" Added Ada support. (thanks to Preben Randhol)
" Added Latte support.
" Added blocksupport and possibility to specify action (comment or
" decomment). It's also possible to guess the action line by line or
" using the first line of a block.
" Thanks to Xiangjiang Ma and John Orr for the rich feedback on these
" issues.
" Decomments /*foo();*/, when PrettyComments is set.
" Added 'vhdl' and 'verilog'. (thanks to Steve Butts)
" 1.7
" Added different options to control behaviour of the plugin.
" Changed default Keybindings to proper plugin settings.
" 1.6
" Now supports 'm4', 'config', 'automake'
" 'vb', 'aspvbs', 'plsql' (thanks to Zak Beck)
" 1.5
" Now supports 'java', 'xml', 'jproperties'. (thanks to Scott Stirling)
" 1.4
" Lines containing only whitespace are now considered empty.
" Added Tcl support.
" Multipart comments are now escaped with configurable alternative
" strings. Prevents nesting errors (eg. /**/*/ in C)
" 1.3
" Doesn't break lines like
" foo(); /* bar */
" when doing commentify.
" Install Details:
" Simply drop this file into your $HOME/.vim/plugin directory.
