Usage: frs [COMMAND]
Commands:
help Print this message or the help of the given subcommand(s)
inspect Inspect context
run Run with context
save Save context
with Manipulate context
The frs with command can be extended using any programming language. To create an frs extension, you must create a program that reads the context either from a file system path or stdin and produces an exact context in JSON format.

$ frs with ext -- python script/activate.py -- customized_arguments...
λ(app) :: ext(python:activate)
$ python script/activate.py --from-file ~/.confg/frs/context/default/app.json customized_arguments... # the underlying commandThe program should output a JSON object that represents the context, similar to the following example:
{"meta":{"step_log":[{"description":"core::context \"app\"","prompt":"activate ..\"app\""}]},...}
