This is the new crunch utility for making distribution floppies from

James da Silva.  We need to integrate this before 1.1.5 so that we can
actually make the boot floppies.

+.Sh NAME
+.Nm crunchide
+.Nd hides symbol names from ld, for crunching programs together
+.Sh SYNOPSIS
+.Nm crunchide
+.Op Fl f Ar keep-list-file
+.Op Fl k Ar keep-symbol
+.Op Ar object-file ...
+.Sh DESCRIPTION
+
+.Nm Crunchide
+hides the global symbols of
+.Ar object-file
+such that they are ignored by subsequent runs of the linker, 
+.Xr ld 1 .
+Some symbols may be left visible via the
+.Fl k Ar keep-symbol
+and 
+.Fl f Ar keep-list-file
+options.  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>.
