Blah (Bibtex to LaTeX and HTML).
The bibliographies in this page and in my cv are both generated from a bib file (sample) using
this Perl script I wrote. Blah supports several features that I could not find in the other 127 solutions available online, see the documentation at the beginning of the script.
Flexiblemathdisplay redefines \[ \] to automatically switch between equation, multline*, etc.
Theomac, to restate theorems.
Bibspacing, to remove spaces between bibliographic entries.
