This module includes different generator directives. It includes alignment
directives (left_align[], center[], and right_align[]), repetition (repeat[]), directives controlling automatic delimiting
(verbatim[],
no_delimit[],
and delimit[]),
controlling case sensitivity (upper[] and lower[]), field width (maxwidth[]), buffering (buffer[]), splitting into columns (columns[])
and attribute handling (duplicate[], omit[], and skip[]).
