# This is a partial python port of nsinstall.
|
|
# It's intended to be used when there's no natively compile nsinstall
|
|
# available, and doesn't intend to be fully equivalent.
|
|
# Its major use is for l10n repackaging on systems that don't have
|
|
# a full build environment set up.
|
|
# The basic limitation is, it doesn't even try to link and ignores
|
|
# all related options.
