[ccp4bb] polygon stand alone - updated version

[Alexandre Urzhumtsev]

Hello,

An updated stand-alone version of the program POLYGON (Urzhumtseva et al., 
2009, Acta Cryst, D65, 297-300) is available at

http://www-ibmc.u-strasbg.fr/arn/Site_UPR9002/Polygon/Polygon.html

A number of "bugs" were fixed; in particular this version was successfully 
tested at a Mac computer (in addition to linux and Windows).

Best regards,

Sacha
