Request for Opinion - JCL but for Linux??

Any interest in this:

LJL is a job creation language that takes a job file, gathers items mentioned in its various lines and here-documents, and generates a runnable .deck file (short for "deck of cards").

The .deck file is a complex Bash script that creates a log spool and several temporary files in /tmp/

<jobname>

Any questions about it? Any suggestions?
