The configuration file supports comments, with #
character used as start comment section. The comment character can be
present at the start of the line or inline.
Extra care should be considered when using # in
character tokenization settings as everything after it will not be taken
into consideration. To avoid this, use # UTF-8 which is
U+23.
# can also be escaped using \. Escaping is
required if # is present in database credential in source
declarations.
