# This is a B-to-C translator, designed to be called from a makefile as:
#   .b.c:  ;b-c 0-6t 7-9 <$*.b >$@
# What this command does is enable all lines that start with ":0" thru ":6" or
# ":t" and disable all lines that start with ":7" thru ":9".  We also look for
# an initial line of the form:
#    static char ID[] = "@(#) foobar %D";
# We replace the %D with the date.  This should convert  a  foo.b  file  to  a
# compilable  foo.c  file,  with an ID string containing the current date, and
# with debug lines ":0" thru ":6" enabled.
