- reorg 07/19/92
-
- This is version 1 of the 'reorg' program. Part of the shareware
- package VHlogger from Vincent Herried (KA8CTE). Copyright 1992
- Vincent Herried. See the copyright files for additional information.
-
- Acknowledgments to Marcus J. Ranum for his B Tree package without which
- I doublt that I would have ever written this package. Please see
- the btree copyright file.

- Version history:
-
- V1.0 07/19/92 Initial public release.
-
- Functions:
-
- The btree implimented with this package does not release unused space
- from the files when you update a record. If you make a lot of updates
- and you think your data base files are getting too big, then this
- program is for you.
-
-
- Useage from the CLI:
- reorg -i input -o output [-p nnnn]
-
-
- The input data base named input.ndx and input.dat is reorganized and copied
- to output.ndx and output.dat. In addition to removing the gas from the files
- they btree structure is turned on its side in an attempt to 'optomize' the
- tree structure. So even if you haven't updated a lot of records, you may
- wish to run reorg on a new data base that you have just increased the
- number of records by more than 30 or 40 %. It is supposed to give you
- better access times.
-
- The -p option changes the internal index page size. Don't use it
- unless you wish to fiddle with performance and have looked at the
- btree algorithms.
-
- It is suggested that the location of the input and output be on
- different devices. eg: reorg -i df0:vhlog -o df1:vhlog
