PDB Plugin, Version 0.1

This plugin reads and writes molecular coordinate data stored in the PDB file format.

Feature-specific notes:

Since PDB files can only store 99,999 atoms without overrunning the columns designated for atom indices etc, the PDB plugin doesn't directly use the atom indices specified in the PDB file as its own indices, instead it keeps its own independent atom index counter, allowing it to read files containing millions of atoms. The atom index field for atoms beyond 99,999 may contain alphanumeric characters, or some other unique string scheme, as has commonly been used in software such as X-PLOR/CNS, and other packages.

Unused data
Various PDB record types and fields are ignored by VMD, in general VMD doesn't do anything with the sequence data or crystallography-specific fields in the format, though it does read in unit cell information for use with periodic image display when possible.
