otags 3.12.5-2 (i386 binary) in ubuntu trusty

 Otags generates "tags" files for emacs and vi/vim to give these
 editors the ability to directly jump to function and value
 definitions. Otags is based on Camlp4. It can load all Camlp4 syntax
 extentions and can therefore parse all sources that Camlp4 can parse
 (including standard and revised syntax).
