# 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.
