#
# User package installer for CentOS (and RedHat and Fedhora)
# Developped on CentOS 6.5
# You can use Miniconda as a complementary package manager.
# I recommend Miniconda 3 over Miniconda 2.
#
# # Usage
# To download one or several package:
#     make +screen
#     make +zsh +tcl
# To install all downloaded packages:
#     make install
#
# To print the configuration to use in your `.profile`:
#     make environment
#
# You can uninstall the whole system at any moment just by deleting the
# $(ROOT_D) directory (see configuration).
#
# Note that at the moment, the system doesn't support package removal so any
# addition is definitive.
#
#  * If you did `make +the_wrong_package_name` but did not do `make install`,
#    you can still cancel the installation by dropping your cache:
#
#    (replace ROOT_D by the value you configured)
#    `rm -r $ROOT_D/rpm $ROOT_D/dwnldlist`
#
#    You can also use `make unload`. It does the same.
#
#    Either way, you'll lose your cache so
