Function

   Validate index and report internals for dbx databases

Description

   dbxreport reports statistics for the index fields of a database.

Algorithm

   The index directory is, by default, the index directory af an installed
   database.

   dbxreport reads the index file, reporting on the file name, the number
   of index terms, the depth of the index tree, statistics of internal
   page types and the free space in an uncompressed index.

Usage

   Here is a sample session with dbxreport


% dbxreport -indexdir .
Validate index and report internals for dbx databases
EMBOSS database name: embl
Index fields [id]: id,acc
Output file [embl.dbxreport]:
