This file is a reminder concerning major known problems with POLYS:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

1. energy minimizer does not at present work properly (SBE 2013)

2. fix pdb format
	- The pdb format written by polys does not 
          conform to the standard. This confuses the
          viewing programs. 

3. handle unused return values
    - for now I stored them in an 'int unused;' variable, but this
      return value should be checked.

4. The ATTACH command is not finished and will need a new case_input file
