# (or beginNAME for environment with no the backslash)

# or to an array (specified as [rule,rule,...]) of length N where
# N is the number of parameters to be read with the macro. The
# array values tell how each is to be interpreted (see the parser state
# keywords for valid values). Thus specifying a number N is
# equivalent to specifying an array of N 'ignore' rules.
#
# For macros not specified here, the default value is 0: i.e.
# no tokens are excluded, but [...] options are.
