Mon Jan 30 xx:xx:xx 2001 Dorai Sitaram * packaged for CTAN Sat Nov 11 20:00:00 2000 Dorai Sitaram * Version 2.8.1 * \leftdisplays was not allowing pagebreaks inside \eqalignno. Bug reported by Ludger Hentschel . Fixed by Donald Arsenau . * doc/btxdoc.bib included alongside doc/btxdoc.tex Sat Sep 2 13:20:00 2000 Dorai Sitaram * Version 2.8 Sun May 7 09:40:00 2000 Dorai Sitaram * Fixed problem where Eplain's redefinition of \iterate was causing nameclash of \next in a TeXdraw macro. Suggested by TeXdraw author Peter Kabal . Sat Apr 9 00:17:00 2000 Adam Lewenberg * xeplain.tex: Fixed problem introduced when double column uneven bug was `fixed'. Sun Apr 25 22:30:00 1999 Adam Lewenberg * doc/progdef.texi: Added a section on user-defined environments to progdef.texi and fixed a few typos in documentation. Suggested by Paul Abrahams. Thu May 14 11:30:00 1998 Adam Lewenberg * xeplain.tex: Changed \columnfill after suggestion of Helmut Jarausch . Wed Dec 5 09:10:00 1997 Adam Lewenberg * Version 2.7. * xeplain.tex: Added the control sequence \gutterbox as a hook to add arbitrary vertical material between columns in multi-column mode. Wed Mar 26 07:17:00 1997 Adam Lewenberg * xeplain.tex: Moved an \obeywhitespace to the end of the definition of \verbatim to remove spurious space. Suggested by Dorai Sitaram. Wed Jan 28 08:00:00 1997 Adam Lewenberg * xeplain.tex: Added \def\@emptymarkA{\@emptymarkB} so that \ifempty\undefined is false. Suggested by Stanislav Brabec. Sat Oct 5 18:11:00 1996 Adam Lewenberg * xeplain.tex: Changed a line in the definition of \@fineqdefn to remove a \noexpand which seemed to be causing a problem with \eqdef. Tue Sep 24 10:25:00 1996 Adam Lewenberg * xeplain.tex: Added some code to multiple columns so that when switching from multi- to single-columns the last line or so does not get lost. Let's hope it works; added a \newif. Wed Apr 1 10:11:00 1996 Adam Lewenberg * arrow.tex: changed \smash to \smash@@ (a synonym for plain's smash) so that arrow.tex works with amstex. * xeplain.tex: Put a test at the start so that eplain.tex is loaded only once. * xeplain.tex: changed -1in to -1truein in margin macros; Macros affected: \@finishtopmargin \@finishleftmargin \@computebottommargin \@computerightmargin \indexsetmargins. Also, initialize \paperheight to 11truein and \paperwidth to 8.5truein when \mag is not 1000. These changes forced a redefinition of \magnification in the event that \magnification is called AFTER eplain.tex is \input (in particular, when \magnification is used with an eplain .fmt). * xeplain.tex: changed {toc} to {#1} in the definition of \readcontentsfile to allow more general use. * merge: the merge script improperly replaced "xeplain" by "eplain" in too many places.

Use \if@citewarning here, so the \if's and \fi's match properly. * eplain.texinfo (Citations): document \xrefwarningtrue. (Cross-references): ditto. * xeplain.tex (\ifxrefwarning): define to be \if@citewarning, so changes to the latter are reflected in the former. Sat Nov 24 08:21:35 1990 Karl Berry (karl at hayley) * xeplain.tex: say that we have two version numbers now in the header comment. Thu Nov 22 10:48:35 1990 Karl Berry (karl at hayley) * eplain.texinfo (Equation references): \eqdef can be used in an \eqalignno now, so \eqdefn is useful in even fewer sitations. Thu Nov 15 10:28:13 1990 Karl Berry (karl at hayley) * Version 1.5. * merge: remove comments from xeplain.tex as well as btxmac.tex, and fix the checksum and filename in the final eplain.tex. * xeplain.tex (\if@fileexists, ...): \let = \relax, in case the file is being read twice. * Makefile (etex.fmt): new rule. Wed Nov 14 19:02:28 1990 Karl Berry (karl at aten) * eplain.texinfo (Iterations): fix syntax error in example (from bsuggs@hac2arpa.hac.com).

Sat Oct 27 09:46:54 1990 Karl Berry (karl at hayley) * eplain.tex becomes xeplain.tex; a shell script `merge' puts definitions from btxmac.tex that are used in the rest of eplain into xeplain, creating eplain.tex. Also, a new conditional, \ifnobibtex, determines whether we read btxmac.tex or not. (Being able to not read btxmac suggested by Paul.) Sun Oct 21 14:03:31 1990 Karl Berry (karl at hayley) * eplain.texinfo (Cross-references): users should use \@setmoreletters, not redefine \@setletters. Wed Oct 17 07:14:26 1990 Karl Berry (karl at hayley) * eplain.tex (\eqdef): don't do \eqno if we're inner.
