+================
+
+Name
+----
+makechrootpkg - Build a PKGBUILD in a given chroot environment
+
+Synopsis
+--------
+makechrootpkg [OPTIONS] -r <chrootdir> [--] [makepkg args]
+
+Description
+-----------
+
+Run this script in a directory containing a PKGBUILD to build a package
+inside a clean chroot. Arguments passed to this script after the
+end-of-options marker (--) will be passed to makepkg.
+
+The chroot dir consists of the following directories:
+<chrootdir>/{root, copy} but only "root" is required
+by default. The working copy will be created as needed
+
+The chroot "root" directory must be created via the following
+command:
+	mkarchroot <chrootdir>/root base-devel
+
+This script reads {SRC,SRCPKG,PKG,LOG}DEST, MAKEFLAGS and PACKAGER
+from makepkg.conf(5), if those variables are not part of the
+environment.
+
+Default makepkg args: --syncdeps --noconfirm --log --holdver --skipinteg
