+#
+# march 2014
+# added ghostscript and graphicsmagick as dependencies 
+# fixed a wierd problem where gs was trying to use the new_files_path from universe (database/tmp) as ./database/tmp
+# errors ensued
+#
+# august 2013
+# found a problem with GS if $TMP or $TEMP missing - now inject /tmp and warn
+#
+# july 2013
+# added ability to combine images and individual log files into html output
+# just make sure there's a log file foo.log and it will be output
+# together with all images named like "foo_*.pdf
+# otherwise old format for html
+#
+# January 2013
+# problem pointed out by Carlos Borroto
+# added escaping for <>$ - thought I did that ages ago...
+#
+# August 11 2012 
+# changed to use shell=False and cl as a sequence
+
+# This is a Galaxy tool factory for simple scripts in python, R or whatever ails ye.
+# It also serves as the wrapper for the new tool.
+# 
+# you paste and run your script
+# Only works for simple scripts that read one input from the history.
+# Optionally can write one new history dataset,
+# and optionally collect any number of outputs into links on an autogenerated HTML page.
+
+# DO NOT install on a public or important site - please.
+
+# installed generated tools are fine if the script is safe.
+# They just run normally and their user cannot do anything unusually insecure
+# but please, practice safe toolshed.
+# Read the fucking code before you install any tool 
+# especially this one
+
+# After you get the script working on some test data, you can
+# optionally generate a toolshed compatible gzip file
+# containing your script safely wrapped as an ordinary Galaxy script in your local toolshed for
+# safe and largely automated installation in a production Galaxy.
+
+# If you opt for an HTML output, you get all the script outputs arranged
+# as a single Html history item - all output files are linked, thumbnails for all the pdfs.
+# Ugly but really inexpensive.
+# 
+# Patches appreciated please. 
+#
+#
+# long route to June 2012 product
+# Behold the awesome power of Galaxy and the toolshed with the tool factory to bind them
+# derived from an integrated script model  
+# called rgBaseScriptWrapper.py
+# Note to the unwary:
+#   This tool allows arbitrary scripting on your Galaxy as the Galaxy user
+#   There is nothing stopping a malicious user doing whatever they choose
+#   Extremely dangerous!!
+#   Totally insecure. So, trusted users only
+#
+# preferred model is a developer using their throw away workstation instance - ie a private site.
+# no real risk. The universe_wsgi.ini admin_users string is checked - only admin users are permitted to run this tool.
