       -w, --warning
	   Show warning on substitution operation resulting in no content change on every file. The default is to show a warning on substitution

	%install
	    shtool subst -v -n 
		-e 's;^(prefix=).*;1 $RPM_BUILD_ROOT%{_prefix};g' 
		-e 's;^(sysconfdir=).*;1 $RPM_BUILD_ROOT%{_prefix}/etc;g'

	    make install

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.

NAME

       shtool-mkdir - GNU shtool mkdir(1) style command

SYNOPSIS

       shtool mkdir [-t|--trace] [-f|--force] [-p|--parents] [-m|--mode mode] [-o|--owner owner] [-g|--group group] dir [dir ...]

DESCRIPTION

       This is a mkdir(1) style command with additional options and the ability to be smart if the directory already exists which is important for
       installation procedures.

OPTIONS

       The following command line options are available.

       -t, --trace
	   Shows the actually involved shell commands.

       -f, --force
	   Forced continuation and no complaints if directory already exists.  Default is to terminate with error.

       -p, --parents
	   Automatic parent directory creation. Default is to only create the last directory in the path and fail if parents are missing.

       -m, --mode mode
	   The directory mode applied to the directory, see chmod(1). Omitting mode skips this step and leaves the operating system default which
	   is usually based on umask(1). Some directory modes require superuser privileges to be set. Default is to stick with operating system
	   defaults.

       -o, --owner owner
	   The directory owner name or id applied to the directory, see chown(1).  This option requires superuser privileges to execute. Default
	   is to skip this step and leave the operating system default which is usually based on the executing uid or the parent setuid directory.

       -g, --group group
	   The directory group name or id applied to the directory, see chgrp(1). This option requires superuser privileges to execute to the
	   fullest extend, otherwise the choice of group is limited on most operating systems.	Default is to skip this step and leave the
	   operating system default which is usually based on the executing gid or the parent setgid directory.

EXAMPLE

	#   Makefile
	install:
	    shtool mkdir -f -p -m 755 $(bindir)
	    shtool mkdir -f -p -m 755 $(mandir)/man1
	     :

HISTORY

       The GNU shtool mkdir command was originally written for Public Domain by Noah Friedman and later revised by Ralf S. Engelschall
       <rse@engelschall.com> in 1999 for inclusion into GNU shtool.
