It is not documented but you can run Curl scripts using the 'curl' executable that is included in he Surge Lab download.

For instance, here is a trivial script that
outputs its args:

echo.xcurl:
{curl 1.5 script}
{for arg in script-args do {output arg}}

$ curl echo.xcurl hi there
hi there

You can also run the 'curl' program interactively using the --shell argument.
