Oh, I'd appreciate any tips you might have.

The pkgsrc documentation, while extensive, is not a tutorial, so I find myself
a little lost.  I've been working off of examples, but some things puzzle me.
For example, CFS uses a variable "CRYPTO=" and there's no explanation of what
this means anywhere that I've seen.

The package I'm working on is available here:

Could you take a look at it?
