GENERAL COMMENTS ABOUT EAGLE COMPONENT LIBRARIES ================================================ The component libraries supplied with EAGLE have been compiled with great care as an additional service to you, our customer. However, the large number of available components and suppliers of these components means that the occasional discrepancy is unavoidable. Please note, therefore, that CadSoft takes no responsibility for the complete accuracy of information included in library files. Please note that libraries are not necessarily identical to former libraries with the same name. Therefore, it is advisable to back up your old libraries before installing the new ones. Additional new libraries, that have not yet been officially released, can be found on CadSoft's internet site in the download section (www.cadsoftusa.com). Please note, that libraries can be edited very conveniently with the commands EXPORT and SCRIPT. All packages are defined in such a way, that tNames contains the names of the components and tPlace contains the additional pc board print. For the documentation print, tDocu is selected additionally. This layer contains graphical objects which must not be printed onto the board. If components are placed on the bottom side of the board, the related information changes from t.. to b.. layers (e.g. from tNames to bNames). Further usage of layers: Holes: mounting holes t/bFinish: finish, e.g. AT-Slot t/bStop: areas without solder stop mask, e.g. for bridging connections t/bRestrict: area without tracks, e.g. around mounting holes t/bKeepout: area without components, e.g. EURO-19"
