This directory contains scripts to be executed by the EOS workflow engine.
These scripts should be installed in the following directory on the EOS
mgm node:

    /var/eos/wfe/bash/

For example the following script is executed when a tape server triggers
an archived.default workflow event:

    /var/eos/wfe/bash/create_tape_drop_disk_replicas

The following "eos attr set" commands can be used to build the workflow
actions of an EOSi/CTA instance.  Please remember to replace
CTA_WF_DIR with the path specific to you're EOS instance, for example
/eos/dev/proc/cta/workflow.  Please also replace CTA_BIN with the full
path of the cta command-line tool.
