=head1 NAME
svn-clean - Wipes out unversioned files from Subversion working copy
=head1 SYNOPSIS
svn-clean [options] [directory or file ...]
=head1 DESCRIPTION
B<svn-clean> will scan the given files and directories recursively and find
unversioned files and directories (files and directories that are not present in
the Subversion repository). After the scan is done, these files and directories
will be deleted.
If no file or directory is given, B<svn-clean> defaults to the current directory
(".").
B<svn-clean> uses the SVN Perl modules if they are available. This is much
faster than parsing the output of the B<svn> command-line client.
=head1 OPTIONS
=over 8
=item B<-e>, B<--exclude>
A regular expression for filenames to be exluded. For example, the following
command will skip files ending in ".zip":
=over 8
svn-clean --exclude '\.zip$'
=back
Multiple exclude patterns can be specified. If at least one matches, then the
file is skipped. For example, the following command will skip files ending in
".jpg" or ".png":
=over 8
svn-clean --exclude '\.jpg$' --exclude '\.png$'
=back
The following command will skip the entire "build" subdirectory:
=over 8
svn-clean --exclude '^build(/|$)'
=back
=item B<-f>, B<--force>
Files to which you do not have delete access (if running under VMS) or write
access (if running under another OS) will not be deleted unless you use this
option.
=item B<-N>, B<--non-recursive>
Do not search recursively for unversioned files and directories. Unversioned
directories will still be deleted along with all their contents.
=item B<-q>, B<--quiet>
Do not print progress info. In particular, do not print a message each time a
file is examined, giving the name of the file, and indicating whether "rmdir" or
"unlink" is used to remove it, or that it's skipped.
=item B<-p>, B<--print>
Do not delete anything. Instead, print the name of every file and directory that
would have been deleted.
=item B<-?>, B<-h>, B<--help>
Prints a brief help message and exits.
=item B<--man>
Prints the manual page and exits.
