+# NAME
+# 	build-ci.sh - An automated tool to build a pacman repository out of PKGBUILDs
+#
+# SYNOPSIS
+# 	build-ci.sh
+#
+# DESCRIPTION
+# 	Build the PKGBUILDs into a pacman repository
+# 	
+# 	The PKGBUILDs are assumed to be placed in a similar structure:
+#
+# 	```
+# 	|- $SRC_DIR
+# 	    |- (package name)
+#	        |- PKGBUILD
+# 	        |- .SRCINFO
+# 	```
+#
+# 	$SRCDIR is $(pwd) by default, but you can set it to your own path like this:
+# 	
+# 	```bash
+# 	$ SRCDIR=/path/to/src/dir build-ci.sh
+# 	```
+#
+# 	Also this script accepts a number of other arguments to be set via environemt variable:
+#
+#	**SUDO_PASS**  - Sudo password to run commands as root		(required)
+#	**MAKE_CACHE** - Directory for cached files			(default: $(pwd)/alc_make_cache)
+#	**TARGET_DIR** - Directory to output the repository		(default: $(pwd)/target)
+#	**SRC_DIR**    - Directory to take packages from		(default: $(pwd)/packages)
+#	**CLEAN_MAKE_DIR** - Whether to clean the cache directory	(default: true)
+# DEPENDENCIES
+# 	This script has the following dependencies:
+# 	bash, [, wc, rm, mkdir, mkarchroot
+#
+# 	The arch packages for these commands are:
+# 	`coreutils devtools`
+
