# This script creates a plugin from the template directory.
# The plugin will have for id (slaying field in events) the first argument,
# and for name an optional second argument, or the id.
#
# Running multiple times this script will erase generated/modified
# plugin, but should not mess too much with building process.
#
# Note that some Crossfire files are affected.
# Ensure everything works before committing :)
#
# Also, modified files (/configure.ac) may have extra new lines.
