Argot is a command-line parser library for Scala, supporting:

• single-value and multi-value options
• single-value and multi-value parameters
• flag and non-flag options
• GNU-style long options, i.e., "--option")
• POSIX-style short options, i.e., single "-" lead-in, with option grouping (e.g., "tar -xcf foo.tgz")
• automatic parameter conversion (i.e., values with non-string types, with automatic conversion)
• the ability to supply your own conversion functions
