other parms are allowed: see man(7), man(1)
-a Use alternate work files. Tells htdig to append .work to database files, causing a second copy of the database to be built. This allows the original files to be used by htsearch during the indexing run.
-c configfile Use the specified configfile instead of the default.
-d Prevent the document index from being created.
-s Print statistics about the document and word databases after htmerge has finished.
-v Run in verbose mode. This will provide some hints as to the progress of the merge. This can be useful when running htmerge interactively since some parts (especially the word database creation) can take a very long time.
-w Prevent the word database from being created.
TMPDIR In addition to the command line options, the environment variable TMPDIR will be used to designate the directory where intermediate files are stored during the sorting process.
@DEFAULT_CONFIG_FILE@ The default configuration file.
