# This script may be used to link an executable with ccmalloc.  It
# automatically tries to filter out requests which do not generate an
# executable binary.  With this script the usage model of ccmalloc becomes
# similar to purify.  Just use 'ccmalloc gcc' wherever you regularly would
# use 'gcc' alone.
