13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	44 Most of the changes in AnaGram 2.40 are under the hood - cleanup of
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	45 source files, reorganization of the source tree, revision of build and
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	46 test procedures, and so forth, in preparation for the open source

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	61 The manual has been re-typeset using LaTeX instead of WordPerfect.
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	62 The typographic consistency and formatting has been considerably
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	63 improved; unfortunately, the pagination is now completely different,
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	64 so page numbers are not portable to the new version.

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	75 The Unix build of the command-line version of AnaGram (agcl) is now
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	76 supported and available to the public. There is at present no GUI for
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	77 the Unix version. The long-term goal is to migrate the AnaGram GUI
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	78 away from the closed (and orphaned) IBM Visual Age class library to
13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	79 something else, probably GTK, so as to support both Windows and Unix.

13d2b8934445 Import AnaGram (near-)release tree into Mercurial. David A. Holland parents: diff changeset	217 versions of AnaGram, if the first token in a rule was the error token,
