# This script configures my ledger source tree on my Mac OS/X machine.
# This is not necessary, however, since I keep all the files necessary
# for building checked in to the source tree.  Users can just type
# './configure && make'.  This script simply sets up the compiler and
# linker flags for all the various build permutations I use for testing
# and profiling.
