+Example (\nextx) is well-known from the literature on parasitic
+gaps.  Here we are concerned with example formatting, not with the
+interesting syntax.
+
+\ex
+I wonder which article John filed {\sl t\/} without reading {\sl e}.
+\xe
+It is beyond the scope of this investigation to determine exactly why
+John did not read the article.
+
+Multipart examples are equally straightforward.
+
+\pex Two examples of parasitic gaps.
+\a He is the man that John did not interview {\sl e\/} before
+he gave the job to {\sl e}.
+\a He is someone who John expected {\sl e\/} to be successful
+though believing {\sl e\/} to be incompetent.
+\xe
+Here, we can speculate on why John did not do an interview before
+recommending the person for a job.  It is likely that the person
+was a crony of John.  In (\lastx b), perhaps John knew that
+the ``someone'' went to prep school with the owner of the
+business.

+If examples and parts of examples are tagged, they can be

+\a This is the man that John interviewed {\sl e\/} before
+telling you that you should give the job to~{\sl e}.
+\a<A> This is someone who John expected {\sl e\/} to be successful
+though believing {\sl e\/} to be incompetent.
+\xe
+
+Now, names can be used.  The name/reference pairs can be written
+to a file, making forward reference possible and backwards
+reference at a distance reliable.  You can refer to part
+\getref{pg.A} of example (\getref{pg}), or (\getfullref{pg.A}).
+
+If you use a tag that has not been defined, {\sl ExPex\/} will
+let you know. If you try to reference a name which has no
+reference, \getref{pg.B} for example, a warning will be issued
+and the (bracketed) tag printed as shown at the beginning of this
+sentence.  If you try to tag a part of an example which has no
+tag, {\sl ExPex\/} will let you know about that as well.

+1.\enspace {\it hom\^{a}o} also means `have', reflecting the
+strong tendency across languages to use the same word for
+possession and the existential. {\it hom\^{a}o} is clause-initial
+in existential clauses, but it comes after the subject in
+possession clauses.
+
+2.\enspace All verbs are glossed with a bare form, as Jarai has
+no inflectional morphology. Although Jarai has lexical items that
+encode tense, they are relatively infrequent in text.
+
+3.\enspace The word {\it laih} is literally `after; finish', but
+that is clearly not the meaning here. Probably {\it laih} here is
+an abbreviation for {\it laih an\u{u}n}, `after that; and', hence
+the gloss `and'.
+
+4.\enspace {\it d\u{o}} `sit, stay' is used like a copula in
+locative clauses, which is what I assume here (`a~peacock
+[which was] beside its nest'); however, this could just as well
+mean `a peacock sitting beside its nest', retaining the posture
+semantics.
