.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBshtool arx\fR is a wrapper around the archiving tool \fBar\fR\|(1). It provides
the ability to create archives out of existing archives, i.e., if one of
\&\fIfile\fR matches "\f(CW\*(C`*.a\*(C'\fR", the archive member files of \fIfile\fR are used
instead of \fIfile\fR itself.
.PP
The trick of this command is the automatic handling of archive members
which is especially interesting if one wants to construct a (usually
top-level) library archive out of pre-built sub-library archives
(usually staying inside subdirs) in a large source tree. For \fB\s-1GNU\s0
libtool\fR based projects, a similar functionality is provided by \fB\s-1GNU\s0
libtool\fR internally, too.

The following command line options are available.

.IX Item "-t, --trace"
Shows the actually involved shell commands.
.IP "\fB\-C\fR, \fB\-\-command\fR \fIcmd\fR" 4
.IX Item "-C, --command cmd"
Set the used \fBar\fR\|(1) command to \fIcmd\fR instead of just \*(L"ar\*(R" (searched in \f(CW$PATH\fR).

.SH "HISTORY"
.IX Header "HISTORY"
The \fB\s-1GNU\s0 shtool\fR \fBarx\fR command was originally written by Ralf S.
Engelschall <rse@engelschall.com> in 1999 for \fB\s-1GNU\s0 shtool\fR. It
was prompted by need to build libraries out of sub-libraries inside the
\&\fB\s-1OSSP\s0\fR project.
