The +.Ar keep-list-file +must contain a list of symbols to keep visible, one symbol per line. +Note that the C compiler prepends an underscore in front of +symbols, so to keep the C function ``foo'' visible, the option +\&``-k _foo'' must be used. + +.Pp +.Nm Crunchide +is designed as a companion program for +.Xr crunchgen 1 , +which automates the process of creating crunched binaries from +multiple component programs. +.Sh SEE ALSO +.Xr crunchgen 1 , +.Xr ld 1 +.Sh AUTHOR +.Nm Crunch +was written by James da Silva <jds@cs.umd.edu>. +.sp 0 +Copyright (c) 1994 University of Maryland.
