extentions to slackpkg for third-party repositories
... the alienbob's compat32 libraries so to have a multilib system without download and install it manually.
Slackpkg+ is NOT a new tool with new commands. The user can continue to use the standard slackpkg command line:
# slackpkg update gpg
# slackpkg update
# slackpkg install openjdk
# slackpkg upgrade-all
etc..
