It allows you to move most of the code from the PKGBUILD into a +template file and uses markers to allow in-place updating of existing PKGBUILDs +if the template has been changed. + +Template files can contain any code allowed in a PKGBUILD. You can think of +them like external files included with "." or "source", but they will be +inlined into the PKGBUILD by 'makepkg-template' so you do not depend on the +template file when building the package. + +Markers are bash comments in the form of: + + # template start; key=value; key2=value2; ... + +and + + # template end; + +Currently used keys are: name (mandatory) and version. Template names are limited to +alphanumerics, "@", "+", ".", "-" and "_". Versions are limited to numbers and ".". + +For initial creation there is a one line short cut which does not need an end marker: + + # template input; key=value; + +Using this short-cut will result in 'makepkg-template' replacing it with start +and end markers and the template code on the first run. + +Template files should be stored in one directory and filenames should be +"$template_name-$version.template" with a symlink "$template_name.template" +pointing to the most recent template. If the version is not set in the marker, +'makepkg-template' will automatically use the most recent version of the +template, otherwise the specified version will be used. This allows for easier +verification of untrusted PKGBUILDs if the template is trusted. You verify the +non-template code and then use a command similar to this: + + diff -u <(makepkg-template -o -) PKGBUILD + +Template files may also contain markers leading to nested templates in the +resulting PKGBUILD. If you use markers in a template, please set the version +you used/tested with in the start/input marker so other people can properly +recreate from templates. + +Options +------- + +*-p, \--input* <build script>:: + Read the package script `build script` instead of the default. + +*-o, \--output* <build script>:: + Write the updated file to `build script` instead of overwriting the input file. + +*-n, \--newest*:: + Always use the newest available template file. + +*\--template-dir* <dir>:: + Change the dir where we are looking for template files. + +Example PKGBUILD +---------------- + + pkgname=perl-config-simple + pkgver=4.58 + pkgrel=1 + pkgdesc="simple configuration file class" + arch=('any') + license=('PerlArtistic' 'GPL') + depends=('perl') + source=("http://search.cpan.org/CPAN/authors/id/S/SH/SHERZODR/Config-Simple-${pkgver}.tar.gz") + md5sums=('f014aec54f0a1e2e880d317180fce502') + _distname="Config-Simple" + + # template start;
