+"""
+This script helps to find expensive templates that are subject to be converted
+to Lua. It counts parser functions and then orders templates by number of these
+and uploads the first n titles or alternatively templates having count()>n.
+
+Parameters:
+-start Will start from the given title (it does not have to exist).
+ Parameter may be given as "-start" or "-start:title".
+ Defaults to '!'.
+-first Returns the first n results in decreasing order of number
+ of hits (or without ordering if used with -nosort)
+ Parameter may be given as "-first" or "-first:n".
+-atleast Returns templates with at least n hits.
+ Parameter may be given as "-atleast" or "-atleast:n".
+-nosort Keeps the original order of templates. Default behaviour is
+ to sort them by decreasing order of count(parserfunctions).
+-save Saves the results. The file is in the form you may upload it
+ to a wikipage. May be given as "-save:<filename>".
+ If it exists, titles will be appended.
+-upload Specify a page in your wiki where results will be uploaded.
+ Parameter may be given as "-upload" or "-upload:title".
+ Say good-bye to previous content if existed.
+Precedence of evaluation: results are first sorted in decreasing order of
+templates, unless nosort is switched on. Then first n templates are taken if
+first is specified, and at last atleast is evaluated. If nosort and first are
+used together, the program will stop at the nth hit without scanning the rest
+of the template namespace. This may be used to run it in more sessions
+(continue with -start next time).
+First is strict. That means if results #90-120 have the same number of parser
+functions and you specify -first:100, only the first 100 will be listed (even
+if atleast is used as well).
+Should you specify neither first nor atleast, all templates using parser
+functions will be listed.
