I'm trying to identify the freely-available Opentype font sets having a consistent Opentype Math font : this kind of font, extremely easy to use with XeTeX and LuaTeX (via
fontspec), can also be used with LibreOffice and Word (a requirement in some administratve setups).
The polish TeX user group GUST has a very active "e-foundry" group, that produced, among others, the "Opentypization" of the "classical Postscript 35", known as the "Tex Gyre" fonts, whose serif fonts have, quite notably, have nice Opentype Math-compatible math fonts.
However, this package is no longer on CTAN (retrieving the link pointed to by the announcement leads to a 404 error, ditto for the CTAN page.
Trying to retrieve it from the home page leads to a login page requesting a GUST ID/Password, notwithstanding the home page statement that
[t]he DejaVu Math font may be freely downloaded. A mail to the GUST webmaster reporting the problem still has to be answered (but that was only two days ago...).
In short, this font seems to have left the surface of the Earth. Hence two questions :
What happened to the CTAN package ?
Are there freely accessible copies somewhere on the Net ? (my Google search gave zilch...).
The first question is the most troubling...
