This package provides two macros which can be used as
building blocks for the parsing of text.  For an example
of their use, see the Calendar package ("calendar.dtx").

The "\@ifoverword" macro takes four arguments.  These
are, in order, a token to match, a text to expand when
a match is found, a text to expand if the match is
not found, and a text to expand if the macro encounters
"\end".  This last is required to allow macros to be
built which will react gracefully when the end of an
environment or a document is encountered.

This macro hops over word units (delimited by a space or spaces),
and expands text according to what it finds on the other side.
Within the text arguments, the "\@overword" can be used to
insert the word that has been gobbled.  The expanded
text can contain the name of the macro that invokes
"\@ifoverword"; which makes it easy to build text-parsing loops.

The package also includes an untested version of "\@ifnextnparchar",
which should ignore "\par" as well as space.

The file "demo.tex" contains a sample of the use of this macro.
This can be used as a model for building text-parsing loops.
