Some documents do not begin with chapter number one, but with chapter
number zero (or even a weirder number). To make the
minitoc
option work with such documents, you must insert the command
\firstchapteris{N>}
before the
\dominitoc and analogous commands. N> is the number
of your first chapter. This command
does not modify the
numbering of chapters, you must use a
\addtocounter{chapter}{-1}
command to get a first chapter numbered 0. The
\firstpartis and
\firstsectionis commands are analogous for parts and
sections with a non standard numbering.
version #17c, these commands are obsolete, as this
problem has been solved. Thus they just give a harmless warning.
