# Sensible Perl-specific RPM build macros.
#
# Note that these depend on the generic filtering system being in place in
# rpm core; but won't cause a build to fail if they're not present.

# This macro unsets several common vars used to control how Makefile.PL (et
# al) build and install packages.  We also set a couple to help some of the
# common systems be less interactive.  This was blatantly stolen from
# cpanminus, and helps building rpms locally when one makes extensive use of
# local::lib, etc.

# Usage, in %build, before "%{__perl} Makefile.PL ..."

# Macros to assist with generating a "-tests" subpackage in a semi-automatic

# The following macros are still in a highly experimental stage and users
# should be aware that the interface and behaviour may change. 
#
# PLEASE, PLEASE CONDITIONALIZE THESE MACROS IF YOU USE THEM.
#
# See http://gist.github.com/284409

# are located under t/, the correct usage is:
#
#   %{?perl_default_subpackage_tests}
#
# If custom files/directories need to be specified, this can be done as such:
#
#   %{?perl_subpackage_tests:%perl_subpackage_tests t/ one/ three.sql}
