+#!/bin/bash
+
+# A simple wrapper script for wkhtmltopdf
+# James Cole: intangi@gmail.com
+# Tweaked slightly by Jethro Carr for suitability purposes.
+
+#What this script does:
+#1. Allows wkhtmltopdf to be used without an X server creating
+#   display numbers randomly to not conflict with other instances
+#   Also doesn't listen on tcp and uses XAUTHORITY files for security
+#2. Optionally accepts html from STDIN
+#3. Dumps to STDOUT if no output file is specified
+#4. All messages are printed via STDERR now so as to not conflict
+#   with piping data
+
+#Depends on Xvfb and wkhtmltopdf
+
+#Make sure wkhtmltopdf is either installed in the path,
+#or it is in the same directory as where you're running this script from.
