# Makefile for xhomer

# To build xhomer:
#
#   1. make clean
#   2. make
#
# To make a new archive tarball, perform the following steps:
#
#   1. make clean
#   2. make date
#   3. make archive

# DGA auto-detection
#
# DGA is used for full-screen modes on XF86 X-servers.  The following
# should auto-detect DGA1 (older systems) or DGA2 (newer systems).
# In case the auto-detection fails, the USE_DGA options immediately
# below may be used to override the detected settings.  This should
# be done by setting one of "USE_DGA1" and "USE_DGA2" to "N" and the
# other to "Y" or by setting both to "N" (most non-Linux systems).

# where you have installed ncurses.

# (at this point, this adds TLB hit statistics)

# id.rom and pro350.rom in the directory it was run from.
