The .vmdsensors file

If VMD is compiled with the VRPN option, it will look for files that specify how to access the external spatial tracking devices. These files are read whenever VMD is told to initialize a specific external device. The Tracker library will look for the following two files, in order:

1. $VMDSENSOR (if the VMDSENSOR environment variable has been set)
2. $HOME/.vmdsensors

In the event of duplicated information, the device specifications found in $HOME/.vmdsensors have precedence over those in $VMDSENSOR.

If none of these are found, the file INSTALLLIBDIR/.vmdsensors will be used instead. This last file contains extensive comments on how to configure the sensor description files properly. If the VRPN option is omitted when compiling VMD, this file is not necessary.
