+makepkg-template - package build templating utility
+
+
+Synopsis
+--------
+'makepkg-template' [options]
+
+
+Description
+-----------
+
+'makepkg-template' is a script to ease the work of maintaining multiple similar
+PKGBUILDs.  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.
+
