Hi All,

    As Lachele pointed out, sleap is buggy at this point and it not ready
for use.

    Our plan is that Qian will do most of the development work and I will
instruct. This time
we will be very careful and make sure that sleap generates exact same
prmtop as tleap does.

    Sincerely,

    Wei
