Nice shortcut to convert from PDF to EPS

From The continuing story of Mac OS X:

To convert pdf → eps (Mac OS X will only do (e)ps → pdf & pdf → ps),

- open the pdf in TeXShop, choose the 'Selection' tool in the Preview window toolbar

- select the desired rectangle (or all, either with ⌘-A or manually),

- choose 'Preview>Save Selection to File...', & save as eps."
