+" Vim indent file generic utility functions
+" Language:    * (various)
+" Maintainer:  Dave Silvia <dsilvia@mchsi.com>
+" Date:        6/30/2004
+
+" SUMMARY:  To use GenericIndent, indent/<your_filename>.vim would have the
+"           following general format:
+"
+"      if exists("b:did_indent") | finish | endif
+"      let b:did_indent = 1
+"      runtime indent/GenericIndent.vim
+"      let b:indentStmts=''
+"      let b:dedentStmts=''
+"      let b:allStmts=''
+"      setlocal indentexpr=GenericIndent()
+"      setlocal indentkeys=<your_keys>
+"      call GenericIndentStmts(<your_stmts>)
+"      call GenericDedentStmts(<your_stmts>)
+"      call GenericAllStmts()
+"
+" END SUMMARY:
+
+" NOTE:  b:indentStmts, b:dedentStmts, and b:allStmts need to be initialized
+"        to '' before callin the functions because 'indent.vim' explicitly
+"        'unlet's b:did_indent.  This means that the lists will compound if
+"        you change back and forth between buffers.  This is true as of
+"        version 6.3, 6/23/2004.
+"
+" NOTE:  By default, GenericIndent is case sensitive.
+"        let b:case_insensitive=1 if you want to ignore case, e.g. DOS batch files
+
+" The function 'GenericIndent' is data driven and handles most all cases of
+" indent checking if you first set up the data.  To use this function follow
+" the example below (taken from the file indent/MuPAD_source.vim)
+"
+" Before you start, source this file in indent/<your_script>.vim to have it
+" define functions for your use.
+"
+"runtime indent/GenericIndent.vim
+"
+" The data is in 5 sets:
+"
+" First, set the data set 'indentexpr' to GenericIndent().
+"
+"setlocal indentexpr=GenericIndent()
+"
+" Second, set the data set 'indentkeys' to the keywords/expressions that need
+" to be checked for 'indenting' _as_ they typed.
+"
+"setlocal indentkeys==end_proc,=else,=then,=elif,=end_if,=end_case,=until,=end_repeat,=end_domain,=end_for,=end_while,=end,o,O
+"
+" NOTE: 'o,O' at the end of the previous line says you wish to be called
+" whenever a newline is placed in the buffer.  This allows the previous line
+" to be checked for indentation parameters.
+"
+" Third, set the data set 'b:indentStmts' to the keywords/expressions that, when
+" they are on a line  _when_  you  _press_  the  _<Enter>_  key,
+" you wish to have the next line indented.
+"
+"call GenericIndentStmts('begin,if,then,else,elif,case,repeat,until,domain,do')
+"
+" Fourth, set the data set 'b:dedentStmts' to the keywords/expressions that, when
+" they are on a line you are currently typing, you wish to have that line
+" 'dedented' (having already been indented because of the previous line's
+" indentation).
+"
+"call GenericDedentStmts('end_proc,then,else,elif,end_if,end_case,until,end_repeat,end_domain,end_for,end_while,end')
+"
+" Fifth, set the data set 'b:allStmts' to the concatenation of the third and
+" fourth data sets, used for checking when more than one keyword/expression
+" is on a line.
+"
+"call GenericAllStmts()
+"
+" NOTE:  GenericIndentStmts uses two variables: 'b:indentStmtOpen' and
+" 'b:indentStmtClose' which default to '\<' and '\>' respectively.  You can
+" set (let) these to any value you wish before calling GenericIndentStmts with
+" your list.  Similarly, GenericDedentStmts uses 'b:dedentStmtOpen' and
+" 'b:dedentStmtClose'.
+"
+" NOTE:  Patterns may be used in the lists passed to Generic[In|De]dentStmts
+" since each element in the list is copied verbatim.
+"
+" Optionally, you can set the DEBUGGING flag within your script to have the
+" debugging messages output.  See below for description.  This can also be set
+" (let) from the command line within your editing buffer.
+"
+"let b:DEBUGGING=1
+"
+" See:
+"      :h runtime
+"      :set runtimepath ?
+" to familiarize yourself with how this works and where you should have this
+" file and your file(s) installed.
+"
+" For help with setting 'indentkeys' see:
+"      :h indentkeys
+" Also, for some good examples see 'indent/sh.vim' and 'indent/vim.vim' as
+" well as files for other languages you may be familiar with.
+"
+"
+" Alternatively, if you'd rather specify yourself, you can enter
+" 'b:indentStmts', 'b:dedentStmts', and 'b:allStmts' 'literally':
+"
+"let b:indentStmts='\<begin\>\|\<if\>\|\<then\>\|\<else\>\|\<elif\>\|\<case\>\|\<repeat\>\|\<until\>\|\<domain\>\|\<do\>'
+"let b:dedentStmts='\<end_proc\>\|\<else\>\|\<elif\>\|\<end_if\>\|\<end_case\>\|\<until\>\|\<end_repeat\>\|\<end_domain\>\|\<end_for\>\|\<end_while\>\|\<end\>'
+"let b:allStmts=b:indentStmts.'\|'.b:dedentStmts
+"
+" This is only useful if you have particularly different parameters for
+" matching each statement.
+
+" RECAP:  From indent/MuPAD_source.vim
