Hi,

as far as I know LELA does not support the same operations as LinBox, it's not 
a straight-forward fork but a re-implementation of a subset (that's my 
understanding, anyway). it has some advantages, i.e., that some bits nicely 
generic, i.e., it should be fairly easy to add new matrix types by adding 
stuff like matrix-matrix multiplication and e.g. PLE decomposition is handled 
generically.

Also, the main developer of LELA Bradford has left academia. He usually 
responds fairly quickly to e-mail and is up for helping out, but as far as I 
know nobody is actively developing LELA at the moment (I might be terribly 
wrong here!)
