Hi,

if you want to package bitmask, you can try:

$ guix import pypi leap.bitmask

This will print a package definition.

You can put it into a file "bitmask.scm" inside the directory $GUIX_PACKAGE_PATH (you may have to set that environment variable first) with the following header:

(define-module (bitmask)
  #:use-module ((guix licenses) #:prefix license:)
  #:use-module (guix packages)
  #:use-module (guix download)
  #:use-module (guix utils)
  #:use-module (guix build-system python)
  #:use-module (guix gexp)
  #:use-module (gnu packages)
  #:use-module (gnu packages base)
  #:use-module (gnu packages cross-base)
  #:use-module (gnu packages pkg-config)
  #:use-module (gnu packages python)
  #:use-module (gnu packages python-xyz))
(define-public python-leap.bitmask

Then you can try it out with

$ guix build --rounds=2 -K python-leap.bitmask

If there are more packages missing, you can generate them all via:

$ guix import pypi -r leap.bitmask

and also put them in the file, adding "(define-public ..." before each block.

For netsplice, it's very similar--but for some reason their package is not
available on PyPI, so you'd have to write the package definition yourself
(just copy the python-leap.bitmask one and modify it - especially the name,
URL and expected checksum - until it works).

If there are any problems please ask on this list.
