Subject: downloads: add basic CVS support
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=15eb1fafa35cd9a9a0bbb70508699bdea1262b01;p=buildroot.git

downloads: add basic CVS support

The support is for pserver mode anonymous CVS.
source-check is based on login since many servers don't support or have
ls/rls disabled.

Usage is pretty straightforward.
PKG_SITE defines the site hostname and remote directory.
The module is defined by the bare package name.
Version is date based.
