# Script to handle alien packages under Debian
|
||||
#
|
||||
# Options:
|
||||
# -p<Patch> Manually specify a patch
|
||||
# -n Build an alien package using heuristics
|
||||
# -g Prepare directories for development
|
||||
# -s Like -g, but prepare single directory for debian-only package
|
||||
# -i Do not install package after building it.
