Today I had to do some profiling of how long each phase of a software install took. The tool I was using printed output like this:

avoid parsing calc HMS forms as ranges: as http://www.mail-archive.com/[email protected]/msg08470.html

write up installing org-mode with aquamacs, including changing path to emacs in Makefile
