-------------------
* add skeleton for CPAN Perl packages, issue 53. Unlike
the PyPI skeleton, it supports a --recursive option to
also generate the recipes for all of the dependencies of
a given module/distribution
* add support for run_test.pl and Perl import tests when
building Perl packages
* add CONDA_PERL environment variable support for
determining which version of Perl to build packages for.
Unlike CONDA_PY, this must include the full version with
periods (e.g., 5.18.2)
* automatically build packages for dependencies if the recipe is
present in the current working directory
* fix a number of Python 3 compatibility issues, issue 59
* work with source files with uppercase suffixes
* switch from chrpath to patchelf on Linux, issue 57
* don't use hard-coded msvc path
* sort import tests from skeleton pypi
