# Notes on building:

# Possible values for DEFS:
#
# By default, flex generates 8-bit scanners when using table compression,
# and 7-bit scanners when using uncompressed tables (-f or -F options).
# For flex to always generate 8-bit scanners, add "-DDEFAULT_CSIZE=256"
# to DEFS.
#
# For Vax/VMS, add "-DVMS" to DEFS.
#
# For MS-DOS, add "-DMS_DOS" to DEFS.  See the directory MISC/MSDOS for
# additional info.

# Run GNU indent on sources. Don't run this unless all the sources compile cleanly.
#
# Whole idea:
#   1. Check for .indent.pro, otherwise indent will use unknown
#      settings, or worse, the GNU defaults.)
#   2. Check that this is GNU indent.
#   3. Make sure to process only the NON-generated .c and .h files.
#   4. Run indent twice per file. The first time is a test.
#      Otherwise, indent overwrites your file even if it fails!
