# pysolv a little software installer demoing the sat solver library/bindings
# things it does:
# - understands globs for package names / dependencies
# - understands .arch suffix
# - repository data caching
# - on demand loading of secondary repository data
# - checksum verification
# - deltarpm support
# - installation of commandline packages
#
# things not yet ported:
# - gpg verification
# - file conflicts
# - fastestmirror implementation
#
# things available in the library but missing from pysolv:
# - vendor policy loading
# - soft locks file handling
# - multi version handling
