It is there already:

 # EASY-INSTALL-ENTRY-SCRIPT: 'pip==1.3.1','console_scripts','pip'

Which says, load the entry point named 'pip' from the 'console_scripts'
entry point group in the 'pip 1.3.1' distribution.

The 'entry_points.txt' metadata file specifies that that entry point is a
function named 'main' inside the 'pip' package itself.
