# This is a simple helper script (/usr/bin/awk wrapper) for debugging the relpipe-tr-awk.

# Captures STDIO and ARGS to log files.

# Add this directory to the $PATH in order to use this wrapper script.

#

# Notes:

#  - if multiple relations are processed, only the last one will stay in the log files (can be solved by adding PID to the log path).

#  - if no relations are processed by the AWK sub-process, the logs will stay unchanged from the last run, although relpipe-tr-awk was executed
