The subdirectories here contain various examples.  To try a particular
example, do the following:

1)  Copy all the files from the example subdirectory directory
    to a new directory which will be your working directory.

2)  "cd" to your working directory.

3)  If there is a Makefile, type "make".
    NOTE:  the environmental variablies BIOSYM and BIOSYM_PLATFORM
    must be defined.

4)  There will be various ".inp" files with the example.  To run these
    type "discovery <file>" where "file" is the leading part of the .inp
    file.  For example, if the BTCL input file is "acenm.inp", type
    "discovery acenm" to run the example.
