Before a counter can be used, it must be created with the macro
tt(NEWCOUNTER). This macro expects one parameter list: the name of the
counter. The initial value of the counter is set to zero.

As for an example, let's say that our macro package should provide two
sectioning commands: tt(section) and tt(subsection). The sections should be
numbered 1, 2, etc., and the subsections 1.1, 1.2, 1.3 etc.. Hence we'd need
two counters:

verb(\
NEWCOUNTER(sectcounter)
NEWCOUNTER(subsectcounter))
