The package provides commands that enable the user (or package writer) to insert punctuation after the macro. The method is similar to that of xspace, but goes further.

The package provides the commands \xperiod, \xcomma and \xperiodcomma, which follow a similar procedure to that of \xspace, and insert punctuation if and only if it is necessary.
