NAME
     ReadPdb - read PDB file
     ReadListPdb - read list of PDB files

SYNOPSIS
     ReadPdb fileName
     ReadListPdb fileName

DESCRIPTION
     Read a PDB file. The file can contain more than one
     structure. If only one structure is stored in the file,
     the file name is taken as name of the molecule. If
     there are multiple structures, numbers are appended
     to the file name for generating the molecule names.

     ReadListPdb expects a file with one file name per line
     (empty lines allowed), and reads all these files.

     If residues appear in the residue library
     ($MOLMOLHOME/setup/amber94.lib by default, can be
     changed with the PathNames command), the covalent
     structure is taken from there. If a residue is not
     present in the library, just the atom coordianates are
     read from the PDB file. The user can add bonds with
     the command CalcBond later.

     The command also reads secondary structure information
     (HELIX and SHEET records) and sets the corresponding
     properties on the residues. They are used by the
     AddRibbon command to create schematic drawings.
