sigil [-i] [-I load-directory] [--eval <CL code>] [--pseval <PS Code>] app.ps > app.js
Run 'make' or './build.sh' to compile sigil. It requires sbcl (or maybe some other Common Lisp but I haven't tried) to be installed, which you can grab from http://www.sbcl.org/platform-table.html, or through something like 'apt-get install sbcl'.
You can 'npm install sigil-cli' (note the underscore) locally into node_modules; the -g option doesn't work yet.
Sigil adds the 'load' command to Parenscript, so you can load macros and other files during compilation, like (load "macros.ps"). Use -I to specify the load paths to search.
Sigil comes with an interactive REPL (Read-Eval-Print-Loop) when invoked with -i (or no arguments), allowing you to type and evaluate Parenscript commands interactively.
