# 1. add check for CLI perl version
# 2. match CLI arg against perlbrew list to determin if exists

#  2. perl lib name - relative path to be appended to PERLLIBS_LIBS, if you
#                     need more then one custom lib per a single installed
#                     perlbrew perl then use lib names like perl-5.12-l1, 
#                     perl-5.12.l2, etc.
#  3. packages details - relative path to be appended to PERLLIBS_CONF
