Each entry is one [help-commands: Custom Command]:
/commandName Text to 'enter into the chat inputbox'
[help-commands:replacements Replacements] (replaced when executing the command):
$1 first command argument (optional, $$1 required), $2- all from second argument, $(stream) named parameter ([help-commands:parameters-context more..])
$urlencode($1-) [help-commands:functions function] to change the input
Escaping (special characters interpreted literally):
Prepend a backslash \ to escape the subsequent character.
\$1 outputs $1 instead of being replaced, \\ outputs \
