rdeps

Find dependencies in ELF objects, recursively if requested.

Output is comma-delimited lines, or JSON

Usage:

Usage: rdeps.py [-r] binary1 [ELF bin1] [ELF bin2] ...

List dependencies for ELF files

-r : Recursively find dependencies, searching RDEPS_PATH

ENVIRONMENT VARIABLES

RDEPS_PATH : colon-delimited directories to search (-r for recursive) for
             dependencies of input files given on command line.
