# All you need to do is source it (from anywhere) and it sets your env up for | |

# commands. It helps with static linking by setting some static library paths | |
# also (See the XXX_STATIC variables) | |
# | |
# It makes assumptions and will try to set things up for you so you can | |
# conveniently build things with or without ./configure based build systems | |
