xpunctuate
package.
Summary description: An extension of the xspace package to include possibly redundant periods and commas. License type: lppl
Announcement text: ----------------------------------------------------------------------
This package affords the user or package writer post-macro punctuation insertion, emph{i.e.}, beyond (but similar to) that of the xspace package. Three new commands are defined: xperiod, xcomma and xperiodcomma, which, following a similar procedure to the standard xspace macro, are designed to insert the relevant punctuation emph{if and only if} necessary.
