# lua
# A powerful, light-weight embeddable programming language.

# Start an interactive Lua shell:
lua

# Execute a Lua script:
lua script_name.lua --optional-argument

# Execute a Lua expression:
lua -e 'print( "Hello World" )'

# All options are handled in order, except -i. For instance, an invocation like
# first set a to 1, then print the value of a (1), and finally run the file script.lua
lua -e'a=1' -e 'print(a)' script.lua
