Artifact 728c547b7e7231f094a1051f9fd68fcebf3d3d1e:

• Executable file bin/fpm-npm — part of check-in [f76d91a812] at 2011-01-04 09:29:15 on branch trunk — - include some more paths in npm packages - set more default values since apt-get barfs on packages with missing data, it seems. Hard to debug since the error messages are totally meaningless. (user: jls@semicomplete.com size: 3168)
