Yes, as I looked into your code, I was even tempted (in thought only, eg subconsciously feasability-checking) to fork/rip your shell syntax parser and plug it into shelljs to replace theirs ;)

To clarify, in my use case, the native asset meta-format for declaring assets and their relationships has a "field" where you can put in an external command to prepare the asset (such as minifying, sass compilation). Like in a Makefile.
