-------------------
0.18 2014-12-17
    - RIBASUSHI++ reminded me that to be a usable directory in @INC we need
      to check -d && -r && -x.

0.17 2014-12-17
    - Fixed RT#96433: ignore directories in @INC which don't exist.
      Apologies to ETHER++ for over-thinking this one,
      and taking so long to fix it.

0.16 2014-12-13
    - Added TODO.md with an initial todo list for the module

0.15 2014-10-14
    - Doing a foreach $dir (@INC) and then resolving symblinks on $dir
      was changing the entries in @INC. HAARG++ for pull request with fix.
    - Changed author email address to be my CPAN email address.

0.14 2014-08-16
    - Added Travis config, using cpanfile and cpanm to ensure all dependencies
      are installed before running tests with prove.
      Thanks to DAGOLDEN.
    - Improved the first paragraph of DESCRIPTION, so search results give
      a better summary of the module.
