For those of you in the habit of building gretl from the CVS sources: later today I'm going to commit a substantial change to the code that underlies gretl's "genr" command. This should offer several benefits (which I'll outline later), but in the short run it's likely that some things will be broken. So if you're using gretl "in earnest", I would not recommend over-writing a working installation of gretl 1.6.0 with a current CVS build at this point. Allin Cottrell
