" Changelog :
"
" 0.2.2 - Security fixes by removing custom tempfile creation
" - Removed need for DiffReviewCleanup/PatchReviewCleanup
" - Better command execution error detection and display
" - Improved diff view and folding by ignoring modelines
" - Improved tab labels display
"
" 0.2.1 - Minor temp directory autodetection logic and cleanup
"
" 0.2 - Removed the need for filterdiff by implemeting it in pure vim script
" - Added DiffReview command for reverse (changed repository to
" pristine state) reviews.
" (PatchReview does pristine repository to patch review)
" - DiffReview does automatic detection and generation of diffs for
" various Source Control systems

" ===========================================================================
" This plugin allows single or multiple, patch or diff based code reviews to
" be easily done in VIM. VIM has :diffpatch command to do single file reviews
" but a) can not handle patch files containing multiple patches or b) do
" automated diff generation for various version control systems. This plugin
" attempts to provide those functionalities. It opens each changed / added or
" removed file diff in new tabs.
"
" Installing:
"
" For a quick start, unzip patchreview.zip into your ~/.vim directory and
" restart Vim.
"
" Details:
"
" Requirements:
"
" 1) VIM 7.0 or higher built with +diff option.
"
" 2) A gnu compatible patch command installed. This is the standard patch
" command on Linux, Mac OS X, *BSD, Cygwin or /usr/bin/gpatch on newer
" Solaris.
"
" 3) Optional (but recommended for speed)
"
" Install patchutils ( http://cyberelk.net/tim/patchutils/ ) for your
" OS. For windows it is availble from Cygwin
"
" http://www.cygwin.com
"
" or GnuWin32
"
" http://gnuwin32.sourceforge.net/
"
" Install:
"
" 1) Extract the zip in your $HOME/.vim or $VIM/vimfiles directory and
" restart vim. The directory location relevant to your platform can be
" seen by running :help add-global-plugin in vim.
"
" 2) Restart vim.
"
" Configuration:
"
" Optionally, specify the locations to these filterdiff and patch commands
" and location of a temporary directory to use in your .vimrc.
"
" let g:patchreview_patch = '/path/to/gnu/patch'
"
" " If you are using filterdiff
" let g:patchreview_filterdiff = '/path/to/filterdiff'
"
"
" Usage:
"
" Please see :help patchreview or :help diffreview for details.
