ruby-hpricot binary package in Ubuntu Precise i386

 Hpricot is a fast, flexible HTML parser written in C. It's designed to be
 very accomodating (like Tanaka Akira's HTree) and to have a very helpful
 library (like some JavaScript libs -- JQuery, Prototype -- give you).
 .
 Also, Hpricot can be handy for reading broken XML files, since many of the
 same principles are used. If a quote is missing, Hpricot tries to figure it
 out. If tags overlap, Hpricot works on sorting them out.
