-#
-# Process INFILE using the C pre-processor and some other programs.
-# Write output to a file named OUTFILE or to the standard output when no
-# OUTFILE has been specified or when OUTFILE is "-". When writing
-# to a file, ignore lines from the input matching the following grep(1)
-# regular expression:
-#
-# ^#include ".*OUTFILE"
-#
-# If there are errors during processing, delete OUTFILE and exit with
-# non-zero status.
-#
-# During snarfing, the pre-processor macro SCM_MAGIC_SNARFER is
-# defined.
-#
-# Optional arg "-d" means grep INFILE for deprecated macros and
-# issue a warning if any are found. Alternatively, "-D" means
-# do the same thing but signal error and exit w/ non-zero status.
-#
-# If env var CPP is set, use its value instead of the C pre-processor
-# determined at Guile configure-time: "@CPP@".
