I don't. My job application e-mail contains a file titled "project experience" (well, actually it's called "Projekterfahrungen", because I currently search a new job in Germany). In that file, I describe each (larger) project I've ever worked on. Something like this:

Blinking Box is the new and enhanced Enterprise class control panel of BigCompany. It features buttons, more buttons, and even colored buttons. And it has nice blinking lights.

My tasks:

• Port from a rotten piece of Fortran to Perl
• Polish buttons and rewire lights
• Set up version control using Subversion
• Documentation
• Whip and spank the trainees

Blinking Box today:

• Lights more shiny than ever before
• Custom buttons for each client
• Best selling product of BigCompany

During the interview, I explain a little more of the details, and how the projects were implemented. And of course, I can always tell them that I wrote the initial Unicode patch for DBD::ODBC. Unfortunately, that's all I could publish from my paid work so far, and it's hard to explain to a full-time interviewer without software developing experience.
