+" Vim support for OCaml .annot files
+"
+" Last Change: 2007 Jul 17
+" Maintainer: Vincent Aravantinos <vincent.aravantinos@gmail.com>
+" License: public domain
+"
+" Originally inspired by 'ocaml-dtypes.vim' by Stefano Zacchiroli.
+" The source code is quite radically different for we not use python anymore.
+" However this plugin should have the exact same behaviour, that's why the
+" following lines are the quite exact copy of Stefano's original plugin :
+"
+" <<
+" Executing Ocaml_print_type(<mode>) function will display in the Vim bottom
+" line(s) the type of an ocaml value getting it from the corresponding .annot
+" file (if any). If Vim is in visual mode, <mode> should be "visual" and the
+" selected ocaml value correspond to the highlighted text, otherwise (<mode>
+" can be anything else) it corresponds to the literal found at the current
+" cursor position.
+"
+" Typing '<LocalLeader>t' (LocalLeader defaults to '\', see :h LocalLeader)
+" will cause " Ocaml_print_type function to be invoked with the right
+" argument depending on the current mode (visual or not).
+" >>
+"
+" If you find something not matching this behaviour, please signal it.
+"
+" Differences are:
+" - no need for python support
+" + plus : more portable
+" + minus: no more lazy parsing, it looks very fast however
+"
+" - ocamlbuild support, ie.
+" + the plugin finds the _build directory and looks for the
+" corresponding file inside;
+" + if the user decides to change the name of the _build directory thanks
+" to the '-build-dir' option of ocamlbuild, the plugin will manage in
+" most cases to find it out (most cases = if the source file has a unique
+" name among your whole project);
+" + if ocamlbuild is not used, the usual behaviour holds; ie. the .annot
+" file should be in the same directory as the source file;
+" + for vim plugin programmers:
+" the variable 'b:_build_dir' contains the inferred path to the build
+" directory, even if this one is not named '_build'.
+"
+" Bonus :
+" - latin1 accents are handled
+" - lists are handled, even on multiple lines, you don't need the visual mode
+" (the cursor must be on the first bracket)
+" - parenthesized expressions, arrays, and structures (ie. '(...)', '[|...|]',
+" and '{...}') are handled the same way
+
+ " Copied from Stefano's original plugin :
+ " <<
+ " .annot ocaml file representation
+ "
+ " File format (copied verbatim from caml-types.el)
+ "
+ " file ::= block *
+ " block ::= position <SP> position <LF> annotation *
+ " position ::= filename <SP> num <SP> num <SP> num
+ " annotation ::= keyword open-paren <LF> <SP> <SP> data <LF> close-paren
+ "
+ " <SP> is a space character (ASCII 0x20)
+ " <LF> is a line-feed character (ASCII 0x0A)
+ " num is a sequence of decimal digits
+ " filename is a string with the lexical conventions of O'Caml
+ " open-paren is an open parenthesis (ASCII 0x28)
+ " close-paren is a closed parenthesis (ASCII 0x29)
+ " data is any sequence of characters where <LF> is always followed by
+ " at least two space characters.
+ "
+ " - in each block, the two positions are respectively the start and the
+ " end of the range described by the block.
+ " - in a position, the filename is the name of the file, the first num
+ " is the line number, the second num is the offset of the beginning
+ " of the line, the third num is the offset of the position itself.
+ " - the char number within the line is the difference between the third
+ " and second nums.
+ "
+ " For the moment, the only possible keyword is \"type\"."
