external-program

This library provides a largely-portable wrapper for running programs external to the Lisp process.

Some caveats:

• some implementations use $PATH, others don’t – the ones that don’t won’t find you bareword commands
• some implementations (EG, Armed Bear) only provide a blocking call, not interactive

There is currently at least some support for:

• Allegro (blocking only)
• Armed Bear (blocking only)
• CLisp
• ClozureCL (née OpenMCL)
• CMUCL
• ECL
• LispWorks
• SBCL

Read the API documention for details. It’s a bit spartan, but should explain a lot. RUN and START are the two primary entrypoints.
