[Gretl-users] hansl in Latex package 'listings'

Hi, by coincidence I've just noticed that the Latex package 'listings' has support for the hansl language already built in. And the file lstdrvrs.pdf from somewhere on the web tells me that this is thanks to Ignacio! This is great. However, it says there (c) 2013, so I'm wondering whether this could use some update? For example, the genr aliases 'matrix', 'scalar' etc. do not appear in the list there. ('listings' was just updated last month after several years, however, so it might take a while to permeate to the public...) Ignacio, if you read this, do you have any hints on how to get changes into the listings package? thanks, sven
