CPAN::HandleConfig - internal configuration handling for CPAN.pm

=cut

);

# Q: where is the "How do I add a new config option" HOWTO?
# A1: svn diff -r 757:758 # where dagolden added test_report [git e997b71de88f1019a1472fc13cb97b1b7f96610f]
# A2: svn diff -r 985:986 # where andk added yaml_module [git 312b6d9b12b1bdec0b6e282d853482145475021f]
# A3: 1. add new config option to %keys below
#     2. add a Pod description in CPAN::FirstTime; it should include a
#        prompt line; see others for examples
#     3. add a "matcher" section in CPAN::FirstTime::init that includes
#        a prompt function; see others for examples
#     4. add config option to documentation section in CPAN.pm
