shtoolize

SHTOOLIZE.TMP(1)					      GNU Portable Shell Tool						  SHTOOLIZE.TMP(1)

NAME

       shtoolize - Build individual GNU shtool scripts

VERSION

       GNU shtool 2.0.8 (18-Jul-2008)

SYNOPSIS

       shtoolize [-h] [-v] [-q] [-o script] module [ module ... ]

DESCRIPTION

       The shtoolize program builds individual GNU shtool scripts (written to the default output file "shtool" or to the specified script) out of
       one or more shtool ingredient modules.  Available modules are:

	echo	   Print string with optional construct expansion
	mdate	   Pretty-print modification time of a file or dir
	table	   Pretty print a field-separated list as a table
	prop	   Display progress with a running propeller
	move	   Move files with simultan substitution
	install    Install a program, script or datafile
	mkdir	   Make one or more directories
	mkln	   Make link with calculation of relative paths
	mkshadow   Make a shadow tree
	fixperm    Fix file permissions inside a source tree
	rotate	   Rotate a logfile
	tarball    Roll distribution tarballs
	subst	   Apply sed(1) substitution operations
	platform   Platform identification utility
	arx	   Extended archive command
	slo	   Separate linker options by library class
	scpp	   Sharing C Pre-Processor
	version    Generate and maintain a version information file
	path	   Deal with program paths

       Additionally there is a pseudo-module ``"all"'' which can be used as a short-hand for ``"echo mdate table prop move install mkdir mkln
       mkshadow fixperm platform arx slo scpp version path"'', i.e. to build a shtool script with all modules in the standard order. An installed
       shtool is usually built this way via ``"shtoolize -o shtool all"''.

       Use the shtoolize program to build individual shtool scripts in case you want a smaller sized script and you don't need all of the
       available shtool functionality.	For instance for the classical Autoconf based free software package a "shtool" script build via
       ``"shtoolize -o shtool install mkdir"'' might be sufficient.

OPTIONS

       The following command line options exist:

       -h  Displays a short help page describing the usage of shtoolize.

       -v  Displays the version number of shtoolize/shtool.

       -q  Displays no processing information.

       -o script
	   Writes the output to file script instead to file ``"shtool"''.

EXAMPLE

       The typical free software package which is based on GNU libtool and GNU shtool one uses a "Makefile" entry like the following:

	#   Makefile entry for upgrading GNU tools
	upgrade-tools:
	    libtoolize -f -c
	    shtoolize -q all

       This upgrades the three files "ltmain.sh", "ltconfig" and "shtool" in the current source tree to the latest versions.

SEE ALSO

       shtool(1).
