Subject: Drop the argparse requirement for make-event-names.py
X-Git-Tag: libevdev-0.9.1~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cea8f0b8cc86332b0643acd62f24f9fef2ecc153;p=platform%2Fupstream%2Flibevdev.git

Drop the argparse requirement for make-event-names.py

We only take one option (path to linux/input.h) anyway so drop the argparse
requirement. This way libevdev builds on RHEL6 too which doesn't ship
argparse.
