# Script will clone, compile and test uclang language interpreter.

# Usage example:
#   bash try_uclang.sh
#   bash try_uclang.sh python lua v8

# PREREQUISITES: bash, git, python2.7, pkg-config, ...

# In case of intention to test modules python, lua and v8, following packages
# are also required: libv8-dev, libpython2.7-dev, liblua5.2-dev, lua-json, ...
