Hi Leonard,

I'm not proposing any changes to the way we handle SlackBuilds from 
SlackBuilds.org - from my earlier post:
> I've had an idea about it which I'll outline here and ask for any comments - its _not_ a proposal for any change at SBo.

My intention was to suggest a general method to handle the setting of 
options _locally_ i.e. by the person building packages, and ask for 
comments on that method. I assumed people would suggest alternatives 
that I could think about and you did that, thank you.

In fact I've since made a three line change to my build tool to do the 
job by processing a new ENVOPTS field which I've added to my local .info 
files, where needed; it looks something like:
     ENVOPTS="ASS=yes BLURAY=yes ... ILBC=no ..."
much like your .env files. The build tool just reads the field and 
exports each element into the environment before running the 
.SlackBuild. I works very well so far.

Thanks again for your input.
