The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$
.\"
If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

.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.
|
|
The names given by
|
|
.Ar keep-symbol
|
|
or in
|
|
.Ar keep-list-file
|
|
should be C names. For example,
|
|
to keep the C function
|
|
.Dq foo
|
|
visible, the option
|
|
.Dq -k foo
|
|
should 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.

|
ELF object support and ECOFF object recognition.
