# usage: epsfig [-c] FILE
#
# Write (possibly compressed) epsfig FILE to stdout.  The TEXINPUTS path is
# searched for FILE{,.gz,z,Z}.  With the -c option the FILE is gziped and
# FILE.bb is generated.  If FILE is in the system default $SYSTEXINPUTS path
# no attempt is made to epsbb it.
#
# Used by epsfig.sty inside backquoted dvips specials.
