# The hack sources are run through several filters before they actually reach

# loaded on a PDP-11).
#
# The filter crypt will read through C source files using a string translation
# table to translate long word(s) into shorter words in C strings.  Xstr
# collects the strings found in a program into a string database, replacing
# multiple occurences of the same string by references to one string in the
# database.  For more information on these filters, see crypt.c and xstr(1).
# Crypt is really crufty and slow, but the goal was to get something out the

#   The make node `depend' has been commented out as the current dependency
# list is [now] not as simple as it used to be ...  The reason for this is
# because xstr(1) screws up on a number of the hack sources for one reason or
# another (see below) and those sources need to have special compile commands
# that run the sources through all the filters except xstr.
#
#   Xstr is unable to handle the construct `char  blah[] = "blah"' because it
# translates it into `char blah[] = &xstr[blah]'.  In one particular case, we
# can't run xstr on hack.rip.c because it translates the multiple lines of the
# tombstone into one line which screws up the tombstone.

# For the moment we are lazy and disregard /usr/include files because
