=head1 DESCRIPTION
B<install-docs> is a tool allow Debian package maintainers to register
documentation to various documentation systems. It currently supports
B<dhelp>, B<dwww>, B<dochelp>, and B<doc-central> browsers.
This manual page provides a quick synopsis of B<install-docs> usage.
Full documentation can be found in the documentation, including a
description of the control file syntax and grammar.

=head1 ACTIONS
Below is list of possible actions B<install-docs> could handle. There can be only one action
option passed to install-docs, moreover the action with its arguments must be the last option
passed.
Each I<file> argument should be the full path for the doc-base control file (i.e.
`/usr/share/doc-base/some_file' or `/etc/doc-base/documents/some_file'), and each
I<docid> should be the document identifier
(Document identifiers are set in the `Document' field of the control file, and usually
correspond to the package name.)
If I<file> or I<docid> equals `B<->' (the minus sign), the list of
arguments is read from the standard input (each file name or document id in separate line).
