[gmx-users] drug-enzyme tutorial

[John Kerrigan]

Hi Stephane,

The drug-enzyme tutorial has been updated and is available at
http://www2.umdnj.edu/~kerrigje/pdf_files/trp_drug_tutor.pdf

Updated input files are available from
http://www2.umdnj.edu/~kerrigje/structbio_II.htm

The solvent, ions, etc have been merged into the "non-protein" group.

However, the file on the prodrg server needs to be updated (or the link
changed to the link given above.)

John
