# POSTDETAILS variable affects the output of command_details.sh.  Setting
# it here silences the output from sourcing command_details.sh.

# Set POSTTARGET to the appropriately-defined post destination. 
 
# The only options for POSTTARGET are 
#POSTTARGET="http://pastebin.com"

# For pastebin, you can set the expiration period.
POSTEXPIRE="1W" # use 1 week as the default, other options are '24h' for a day, etc.

# This file sources the command_details.sh file to leverage all
# of the already-defined functions.  To keep the command_details.sh
# from actually producing output, the main executable statements have
# been wrapped in the equivalent of an ifdef clause, that looks
# for the variable "postdetails" to be defined. -CedarLUG
