.header level    Contents
.paragraph
The DIGS distribution kit consists of one volume, either 
magnetic tape or mountable disk, labeled DIGS.
This
volume contains a single BACKUP save set DIGS.BCK, which contains all the
distribution files from the Fermilab LIB:[LIB.DIGS] directories.
The LIB:[LIB.DIGS]EXPORT procedure is used to generate this distribution
save-set.
.header level    Directory Structure
.paragraph
The DIGS support files are located under the FNAL::LIB:[LIB.DIGS]
directory in the Fermilab Central Computing Facility VAX/VMS system.
The DIGS package occupies several subdirectories of this root directory, as
listed below.
If you are installing DIGS on a system where [LIB.DIGS] cannot be created,
you may place the files under any other
appropriate directory; DIGS maintenance procedures do not depend on the
name of this root directory.

.header level    Installation Procedure

Create a directory under LIB:[LIB.DIGS] to hold the new version of DIGS.
The directory name should reflect the release of DIGS being copied; for
example, DIGS300 

.chapter RELEASE NOTES
.hl Non-essential files
All files in the [DIGS.*] subdirectories may be deleted without affecting
the usage of the DIGS package. This will save approximately 1200
blocks of disk space.
.hl PREVU control
The command parser for PREVU and the other post processor PRINTPP,
treats single blanks as significant separators.
The Cyber version of DIGS treats multiple blanks as a single separator.
The VAX version may be modified to conform with this usage in a future
maintenance release.
