+opk_make.sh - A script to package "something" into a OPK.
+
+Usage:
+  $(basename ${0}) {--directory|-d} <folder> {--opk|-o} <file> [{--help|-h}]
+
+
+Switches:
+  --directory / -d          Sets the folder that is to be used for the resulting opk
+                            to <folder>. This option is mandatory for the script to
+                            function correctly.
+
+  --help / -h               Displays this help text.
+
+  --opkname / -o            Sets the output filename of the resulting opk to <file>.
+                            This option is mandatory for the script to function
+                            correctly.
+
+A version >=4.0 of squashfs is required to be available in your PATH.
