# hm.py: 'Help Me', is a simple wrapper for all build tools.

|
|
# This script was created for the Synergy+ project.

# http://code.google.com/p/synergy-plus
|
|
#
|
|
# The idea behind this is to simplify the build system,
|
|
# however, it's not a dependancy of building Synergy+.
|
|
# In other words, you don't need to use this script!
|
|
#
|
|
# If you don't wish to run this script, simply run:
|
|
# cmake .
|
|
# make
|
|
# This will create an in-source UNIX Makefile.
