+Description: Embedded GNU C Library: Shared libraries [Loongson 2F optimized]
+ Contains the standard libraries that are used by nearly all programs on
+ the system. This package includes shared versions of the standard C
+ library and the standard math library, as well as many others.
+ .
+ This set of libraries is optimized for the Loongson 2F. It only
+ needs to be installed on Lemote Loongson 2F machines. If you install
+ this on a non-Loongson, it won't even be used.
