+====== getopt ======
+  * [[bash]]
+  * [[getopts]]
+  * [[sh]]
+Generally speaking, use ''getopts'' since it is newer and a built-in function of bash.  Use ''getopt'' if you are looking for consistency across platforms.
+The man page has a good example, but here are some of the basics:
+Use **-a:** to requires an argument, either directly after the ''-a'' or with a whitespace first.
+<code>
+getopt a: $*
+</code>
+Use **-b** to set a boolean value.
+<code>
+getopt b $*
+</code>
+=== getopt example ===
+<code bash>
+# Allow -a <arg>, -d and -z
+args=`getopt a:vz $*`
+# If getopt fails, then throw an error and quit
+if [ $? -ne 0 ]; then echo "Usage: ... "; exit 1; fi
+# Set the new arguments
+set -- $args
+while true; do
+  case "$1" in
+  -a)
+    echo "Passed '$2' argument to -a"; shift; shift;;
+  -v)
+    echo "Verbose output enabled"; verbose=1; shift;;
+  -z)
+    echo "Debug output enabled"; verbose=1; debug=1; shift;;
+  --)
+    shift; break;;
+  esac
+done
+</code>
