ack-2.08 - A grep-like program for searching source code

Changes for version 2.08 - 2013-08-22

ENHANCEMENTS
- ack now ignores CMake's build/cache directories by default. Thanks, Volodymyr Medvid.
- Add shebang matching for --lua files.
- Add documentation for --ackrc.
- Add Elixir filetype.
- Add --cathy option. Thanks to Joe McMahon.
- Add some helpful debugging tips when an invalid option is found. Thanks to Charles Lee.
- Ignore PDF files by default, because Perl will detect them as text.
- Ignore .gif, .jpg, .jpeg and .png files. They won't normally be selected, but this is an optimization so that ack doesn't have to open them to know.
FIXES
- Ack's colorizing of output would get confused with multiple sets of parentheses. This has been fixed. (Issue #276)
- Ack would get confused when trying to colorize the output in DOS-format files. This has been fixed. (Issue #145)

ENHANCEMENTS
- We now ignore the node_modules directories created by npm. Thanks, Konrad Borowski.
- --pager without an argument implies --pager=$PAGER.
- --perl now recognizes Plack-style .psgi files. Thanks, Ron Savage.
- Added filetypes for Coffescript, JSON, LESS, and Sass.
FIXES
- Command-line options now override options set in ackrc files.
- ACK_PAGER and ACK_PAGER_COLOR now work as advertised.
- Fix a bug resulting in uninitialized variable warnings when more than one capture group was specified in the search pattern.
- Make sure ack is happy to build and test under cron and other console-less environments.
- Colored output is now supported and on by default on Windows.
