# Slackware build script for xaos
# Written by B. Watson (yalhcru@gmail.com)
# A few notes:
#
# Package really wants to use its own CFLAGS (even checks for them
# in the configure script). Let it...
#
# SFFE is the user formula evaluator, which allows users to define their
# own fractals. On x86 platforms, an assembly-language implementation of
# SFFE is used. On non-x86 platforms, SFFE requires a library called GSL
# (GNU Scientific Library, available from SBo).
#
# xaos is still interesting and useful without SFFE support (most users
# probably don't know/care about the math, so they'll never use the SFFE
# stuff anyway), so we'll just disable it on non-x86 platforms by default.
#
# If you really want to use it, set USE_GSL=yes in the environment before
# running this script. There's no need to use GSL on x86 platforms, since
# the asm code is (or should be) faster, but the option is there if you
# want to use it anyway.
#
# Multilib users also have the option of building on a 32-bit Slackware system
# (or in a chroot) and the resulting package will run just fine on 64-bit.
#
# If the preceding didn't make any sense, here's the bottom line:
#
# - Regular Slackware (x86) users can just run this script and ignore the junk
# above.
#
# - Everyone else (Slamd64, Bluewhite64, Slackware64, ???) can just
# run this script and probably never notice the missing functionality.
#
# - If you're not on x86, but you want the formula evaluator, install GSL
# and then run this script with USE_GSL=yes in the environment.
