-# External templates expect to deal with commands of the form
-#   \command[options]{parameter}
-# while the \inputminted command has the form
-#   \inputminted[options]{language}{filename}
-#
-# In order to use the external templates machinery, the options of the
-# minted package are extended to be able to construct a proper \inputminted
-# command. This template defines an additional 'language' option for minted,
-# which is then extracted from the options and passed as the second non-optional
-# parameter of \inputminted. This template works for minted version 2.1 or
-# higher. As it relies on the internals of minted, an update might break it.

-	Format source code using the 'minted' package.
-	This template works with minted version 2.1 or higher.
-	The source language is specified by the 'language' option,
-	which must be inserted into the 'Option' field in the
-	'LaTeX and LyX options' tab.
-
-	Example options:
-	* linenos,fontsize=\footnotesize,language=fortran
-	* bgcolor=yellow,baselinestretch=1.2,language=c
-	* frame=lines,framesep=2\fboxsep,language=python
-
-	If 'language=xxx' is not given, 'language=latex' is assumed by default.
-	Make sure to use the '-shell-escape' option for the latex backend.
-	Read the documentation of the minted package
-	for further options and details.
