-" Description: insert mode template expander with cursor placement
-"              while preserving filetype indentation.
-"
-"     $Id: imaps.vim 997 2006-03-20 09:45:45Z srinathava $
-"
-" Documentation: {{{
-"
-" Motivation:
-" this script provides a way to generate insert mode mappings which do not
-" suffer from some of the problem of mappings and abbreviations while allowing
-" cursor placement after the expansion. It can alternatively be thought of as
-" a template expander. 
-"
-" Consider an example. If you do
-"
-" imap lhs something
-"
-" then a mapping is set up. However, there will be the following problems:
-" 1. the 'ttimeout' option will generally limit how easily you can type the
-"    lhs. if you type the left hand side too slowly, then the mapping will not
-"    be activated.
-" 2. if you mistype one of the letters of the lhs, then the mapping is
-"    deactivated as soon as you backspace to correct the mistake.
-"
-" If, in order to take care of the above problems, you do instead
-"
-" iab lhs something
-"
-" then the timeout problem is solved and so is the problem of mistyping.
-" however, abbreviations are only expanded after typing a non-word character.
-" which causes problems of cursor placement after the expansion and invariably
-" spurious spaces are inserted.
-" 
-" Usage Example:
-" this script attempts to solve all these problems by providing an emulation
-" of imaps wchich does not suffer from its attendant problems. Because maps
-" are activated without having to press additional characters, therefore
-" cursor placement is possible. furthermore, file-type specific indentation is
-" preserved, because the rhs is expanded as if the rhs is typed in literally
-" by the user.
-"  
-" The script already provides some default mappings. each "mapping" is of the
-" form:
-"
-" call IMAP (lhs, rhs, ft)
-" 
-" Some characters in the RHS have special meaning which help in cursor
-" placement.
-"
-" Example One:
-"
-" 	call IMAP ("bit`", "\\begin{itemize}\<cr>\\item <++>\<cr>\\end{itemize}<++>", "tex")
-" 
-" This effectively sets up the map for "bit`" whenever you edit a latex file.
-" When you type in this sequence of letters, the following text is inserted:
-" 
-" \begin{itemize}
-" \item *
-" \end{itemize}<++>
-"
-" where * shows the cursor position. The cursor position after inserting the
-" text is decided by the position of the first "place-holder". Place holders
-" are special characters which decide cursor placement and movement. In the
-" example above, the place holder characters are <+ and +>. After you have typed
-" in the item, press <C-j> and you will be taken to the next set of <++>'s.
-" Therefore by placing the <++> characters appropriately, you can minimize the
-" use of movement keys.
-"
-" NOTE: Set g:Imap_UsePlaceHolders to 0 to disable placeholders altogether.
-" Set 
-" 	g:Imap_PlaceHolderStart and g:Imap_PlaceHolderEnd
-" to something else if you want different place holder characters.
-" Also, b:Imap_PlaceHolderStart and b:Imap_PlaceHolderEnd override the values
-" of g:Imap_PlaceHolderStart and g:Imap_PlaceHolderEnd respectively. This is
-" useful for setting buffer specific place hoders.
-" 
-" Example Two:
-" You can use the <C-r> command to insert dynamic elements such as dates.
-"	call IMAP ('date`', "\<c-r>=strftime('%b %d %Y')\<cr>", '')
-"
-" sets up the map for date` to insert the current date.
-"
-"--------------------------------------%<--------------------------------------
-" Bonus: This script also provides a command Snip which puts tearoff strings,
-" '----%<----' above and below the visually selected range of lines. The
-" length of the string is chosen to be equal to the longest line in the range.
-" Recommended Usage:
-"   '<,'>Snip

-" ==============================================================================
-" IMAP: Adds a "fake" insert mode mapping. {{{
-"       For example, doing
-"           IMAP('abc', 'def' ft) 
-"       will mean that if the letters abc are pressed in insert mode, then
-"       they will be replaced by def. If ft != '', then the "mapping" will be
-"       specific to the files of type ft. 
-"
-"       Using IMAP has a few advantages over simply doing:
-"           imap abc def
-"       1. with imap, if you begin typing abc, the cursor will not advance and
-"          long as there is a possible completion, the letters a, b, c will be
-"          displayed on on top of the other. using this function avoids that.
-"       2. with imap, if a backspace or arrow key is pressed before completing
-"          the word, then the mapping is lost. this function allows movement. 
-"          (this ofcourse means that this function is only limited to
-"          left-hand-sides which do not have movement keys or unprintable
-"          characters)
-"       It works by only mapping the last character of the left-hand side.
-"       when this character is typed in, then a reverse lookup is done and if
-"       the previous characters consititute the left hand side of the mapping,
-"       the previously typed characters and erased and the right hand side is
-"       inserted
-
-" IMAP: set up a filetype specific mapping.
-" Description:
-"   "maps" the lhs to rhs in files of type 'ft'. If supplied with 2
-"   additional arguments, then those are assumed to be the placeholder
-"   characters in rhs. If unspecified, then the placeholder characters
-"   are assumed to be '<+' and '+>' These placeholder characters in
-"   a:rhs are replaced with the users setting of
-"   [bg]:Imap_PlaceHolderStart and [bg]:Imap_PlaceHolderEnd settings.
