# Why we need these packages?
# - procps contains useful proccess control commands like: free, kill, pkill, ps, top
# - wget is quite basic tool
# - git for using git in our app
# - gcc, libpcre3-dev for compiling uWSGI
# - libffi-dev for installing Python package cffi
# - libssl-dev for installing Python package cryptography
# - vim for online debugging
