" LaTeX stuff
" This makes vim invoke Latex-Suite when you open a tex file.
filetype plugin on

" To install LaTeX-suite:
" aptitude install vim-latexsuite
" sudo vim-addons -w install latex-suite

" Make Latex-Suite compile .tex files to pdf
let g:Tex_DefaultTargetFormat = 'pdf'

" IMPORTANT: grep will sometimes skip displaying the file name if you
" search in a singe file. This will confuse Latex-Suite. Set your grep
" program to always generate a file-name.
set grepprg=grep\ -nH\ $*

" Starting with Vim 7, the filetype of empty .tex files defaults to
" 'plaintex' instead of 'tex', which results in vim-latex not being loaded.
" The following changes the default filetype back to 'tex':
let g:tex_flavor='latex'

" If you write your \label's as \label{fig:something}, then if you
" type in \ref{fig: and press <C-n> you will automatically cycle through
" all the figure labels. Very useful!
