# AngelScript makefile for Linux.
# Type 'make' then 'make install' to complete
# the installation of the library. You no
# longer have to specify SHARED=1 VERSION=x.y.z
# (the Makefile automatically determines it
# and builds it and the static library).
# See README for how to use the shared library
# instead of the static. The README also
# contains other information and in particular
# specifies on how to override the install
# location should you desire this (you don't
# have to - nor should you - edit this
# file).
#
# One note: I don't have a way to test
# the phone builds. I am an old-timer
# and I _still_ miss customer-owned
# coin-operated telephones. In fact
# I still _miss_ the rotary telephone!
