# attempt to check parameters passed to a command
# pre-user-command trigger, defined like this: 
# 
# argcheck command pre-user-.* "%//scripts/triggers/argcheck.sh% %user% %client% %serverid% %quote%%groups%%quote% %command% %argc% %argsQuoted%"
#
# This pre-command trigger fires on any and all commands. 
# The user's group membership (passed using the trigger-script variable "%groups%") is checked for the name specified below as 'this'.
# If found, then we check for a log file called $this.log, write a 'header' to this file if not present, then log the output of the command. 
# Timestamp, username, client serverid, argument count, list of arguments.  
# ----------
# Hardcoded format strings in the printf commands may need to be adjusted to accommodate particularly lengthy naming conventions.
# Not tested for a wide variety of arguments; some strings may result in string- or number-handling errors.
