+# This is a thin wraper arround pygmentize that adds support for SMT-LIB/Alethe.
+# More precicely: it parses the command line arguments and uses a custom
+# SMT-LIB lexer if the user selects smt-lib as the language.
+# This wrapper was made necessary by version 2.7 of minted:  it started to
+# quote command line arguments hended to pygmentize and thereby made the old
+# tick to use "smtlib2.py -x" as the language unworkable.
