# This script reads the syntaces of commands from irssi source tree.
# Then it browses through all '.in' files in the current directory and
# substitutes '@SYNTAX:foo@' tags with real syntaces found. This data
# is written into the corresponding files without the '.in' extension.
# For example: help.in -> ../help
#
# This path has to be changed. It should point to your irssi/src directory
# Remember to include the asterisk ('*').
