texvccheck: use texvc as input verification only.

texvc the input language for formulae in wikipedia has become familiar to wide user range of wikipedia editors. Texvc accepts a selection of LaTeX commands augmented with customized macros as user input. In some cases the input is transformed to html or mathml. But in the majority texvc creates a LaTeX document that is rendered via latex to dvi and then converted to an image. The intermediate tex, dvi and aux files are cleaned up accessible after the conversion is completed.

Facelift for MathSearch

The extension MathSearch [1] has not been maintained for quite a while.
Today, a the code was cleaned up a little bit and the user friendliness was slightly improved.
A new feature, to highlight the the part of the equation that matched, has also been introduced. [2]
It can be tested at [3]. The next steps will be to improve the TextSearch integration and also test alternatives to Lucene.
In the future there will be a MathSearch Category at Bugzilla. At least it has been requested. We'll see how long this will take.
