" Last Change: 2012 Mar 18 19:19:50
" Version: 0.7
" Please email me if you found something we can do. Bug report and
" feature request is welcome.
" Last Update: {{{
" 25th Sep 2002, by LH :
" (*) better support for the option
" (*) use some regex instead of several '||'.
" Oct 9th, 2003, by JT:
" (*) don't change indentation of lines starting with '%'
" 2005/06/15, Moshe Kaminsky <kaminsky AT math.huji.ac.il>
" (*) New variables:
" g:tex_items, g:tex_itemize_env, g:tex_noindent_env
" 2011/3/6, by Zhou YiChao <broken.zhou AT gmail.com>
" (*) Don't change indentation of lines starting with '%'
" I don't see any code with '%' and it doesn't work properly
" so I add some code.
" (*) New features: Add smartindent-like indent for "{}" and "[]".
" (*) New variables: g:tex_indent_brace
" 2011/9/25, by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Bug fix: smartindent-like indent for "[]"
" (*) New features: Align with "&".
" (*) New variable: g:tex_indent_and.
" 2011/10/23 by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Bug fix: improve the smartindent-like indent for "{}" and
" "[]".
" 2012/02/27 by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Bug fix: support default folding marker.
" (*) Indent with "&" is not very handy. Make it not enable by
" default.
" 2012/03/06 by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Modify "&" behavior and make it default again. Now "&"
" won't align when there are more then one "&" in the previous
" line.
" (*) Add indent "\left(" and "\right)"
" (*) Trust user when in "verbatim" and "lstlisting"
" 2012/03/11 by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Modify "&" so that only indent when current line start with
" "&".
" 2012/03/12 by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Modify indentkeys.
" 2012/03/18 by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Add &cpo
" 2013/05/02 by Zhou Yichao <broken.zhou AT gmail.com>
" (*) Fix problem about GetTeXIndent checker. Thank Albert Netymk
" for reporting this.

" Document: {{{
"
" To set the following options (ok, currently it's just one), add a line like
" let g:tex_indent_items = 1
" to your ~/.vimrc.
"
" * g:tex_indent_brace
"
" If this variable is unset or non-zero, it will use smartindent-like style
" for "{}" and "[]"
"
" * g:tex_indent_items
"
" If this variable is set, item-environments are indented like Emacs does
" it, i.e., continuation lines are indented with a shiftwidth.
"
" NOTE: I've already set the variable below; delete the corresponding line
" if you don't like this behaviour.
"
" Per default, it is unset.
"
" set unset
" ----------------------------------------------------------------
" \begin{itemize} \begin{itemize}
" \item blablabla \item blablabla
" bla bla bla bla bla bla
" \item blablabla \item blablabla
" bla bla bla bla bla bla
" \end{itemize} \end{itemize}
"
"
" * g:tex_items
"
" A list of tokens to be considered as commands for the beginning of an item
" command. The tokens should be separated with '\|'. The initial '\' should
" be escaped. The default is '\\bibitem\|\\item'.
"
" * g:tex_itemize_env
"
" A list of environment names, separated with '\|', where the items (item
" commands matching g:tex_items) may appear. The default is
" 'itemize\|description\|enumerate\|thebibliography'.
"
" * g:tex_noindent_env
"
" A list of environment names. separated with '\|', where no indentation is
" required. The default is 'document\|verbatim'.
"
" * g:tex_indent_and
"
" If this variable is unset or zero, vim will try to align the line with first
" "&". This is pretty useful when you use environment like table or align.
" Note that this feature need to search back some line, so vim may become
" a little slow.
