# Slackware build script for dionaea
# based on the SBo SlackBuild template
#
# before building, make sure you have at least python3 and cython installed
# i recommend getting the SlackBuilds from http://slackbuilds.org/

# NOTES:
#   - dionaea will install under /opt/dionaea

# TODO:
#   - figure out a way to include *.pyc (bytecode compiled by the python interpreter)
#     files inside the package, they are generated when dionaea is started
#     - opt/dionaea/lib/dionaea could be completely removed after uninstall?
#   - make $VERSION the actual git revision, not current date
#     - if $VERSION empty, use latest from git, otherwise checkout that revision

# we're trying to conform with FHS 2.3 by using /var/opt/dionaea as localstatedir
# instead of the default /opt/dionaea/var/...

# Slackware 13.1 comes with libnl 1.1 and dionaea would need 2.0 series,
# which has incompatible API. Since libnl IS optional, we'll just skip it

	# HOW TO EDIT THIS FILE:
	# The "handy ruler" below makes it easier to edit a package description.  Line
	# up the first '|' above the ':' following the base package name, and the '|'
	# on the right side marks the last column you can put a character in.  You must
	# make exactly 11 lines for the formatting to be correct.  It's also
	# customary to leave one space after the ':' except on otherwise blank lines.
