tivoli_rpm_to_deb.sh

# Loosely based on the manual steps outlined at:
#   https://kb.berkeley.edu/page.php?id=27401
# and:

#
# This script assumes it is being run on a Debian host that has the alien
# package installed.
#
# This script will process all the RPMs in the current working directory, so
# copy the RPMs you wish to have processed into the current directory and run
# the script. The final DEBs can then be found in the 'debs/' directory.
#
# While the script will attempt to convert all RPMs in the current working
# directory to DEB packages, it has only been tested against the following
# RPMs:
#   gskcrypt64-8.0.14.28.linux.x86_64.rpm (v7.1.0)
#   gskssl64-8.0.14.28.linux.x86_64.rpm (v7.1.0)
#   TIVsm-API64.x86_64.rpm (v7.1.0)
#   TIVsm-BA.x86_64.rpm (v7.1.0)
#
# YOU USE THIS SCRIPT AT YOUR OWN RISK
