=head1 SYNOPSIS

  jats generate_deployable [options]

 Options:

    -help                   - Brief help message

    -help -help             - Detailed help message

    -man                    - Full documentation

    -rtagid=xxx             - Specify the Release Manager RtagId to process

    -rootdir=xxx            - Specifies the root of the releases directory

    -showfilters            - Display current filter set and exit

    -addfilter=xxx[,yyy]    - Add a new filter to the existing filter set

=head1 OPTIONS

=over 8

=item B<-help>

Print a brief help message and exits.

=item B<-help -help>

Print a detailed help message with an explanation for each option.

=item B<-man>

Prints the manual page and exits.

=item B<-rtagid=xxx>

This option specifies one or more RTAG_ID's to use as the source of packages that will be copied.

The ID will be used to get a unique list of package/versions that can be copied from dpkg_archive.

This option is Mandatory, for non-filter command.

=item B<-rootdir=xxx>

This option specifies the root directory where the packages will be copied to.

The specified directory must exist.

The default value is the current directory.

=item B<-showfilters>

This option will display the current filter set. If it is combined with another filter operation 

then the other operations will be performed before the display.

=item B<-addFilter=xxx[,yyy]>

This option allows new filters to be added to the set of filters. This

option can be specified multiple times.

This option specifies a comma separated list of shell wildcard filter rule that

will be used to determine which files are copied from package version directory in

GBE_DPKG to the release directory. This can be supplied multiple times to

specify rules for copying.

Filters must be added the first time this command is run against a release 

and packages are copied to the project/release directory.  These values are then written to a 

config file in the release directory so the same values can be used on subsequent runs.  

In these subsequent runs this option need not be specified as the config items will be used, however

they can be changed by specifying them again on the command line and the config will be re-written.

The values of these will depend on what builds are required for each project.  Some examples are

    --filter='*-WIN32.exe,*.deb'

=item B<-delFilter=xxx[,yyy]>

This option deletes one or more filter rules from an existing set of filters. This

option can be specified multiple times.

=item B<-showfiles>

This option will display the current file set. If it is combined with another file operations

then the other operations will be performed before the display.

=item B<-addFile=xxx[,yyy]>

This option allows new files to be added to the set of kept files. This

option can be specified multiple times.

This option specifies a comma separated list of file names (No wild cards) that

will be used to specify a list of files that shold be kept in the directory. These

files do not form a part of the manifest, but are not deleted by the tool.

=item B<-delFile=xxx[,yyy]>

This option deletes one or more files from the set of kept files. This

option can be specified multiple times.

=item B<-test>

This option will display what would be copied without actually copying anything

=item B<-verbose>

This option will display progress information as the program executes.

=back

=head1 DESCRIPTION

This program is used to update a Distribution 'bin' directory with the versions of

packages as indicated by the specified Deployment Manager SBoms.

There are two modes of operation: Filter modification operations and BOM creation.

In 'Filter modification' mode the current filter set will be updated and the program will

exit.

In BOM creation mode an sbomid must be provided.

The rtagid is used to get all the required information from Release Manager about

which package version are required, as well as the project name and release name.

In addition to using Release Manager information to determine which Package/Versions are

required to be copied this script also uses a set of shell wildcard filters that are

used to determine which files are actually copied when invoked.

The filter rules can be supplied on the command line if available read from a 

configuration file saved in the output diretory the last time the script was run

on this release directory.

One or more filter rules must be specified on the command line the first time this command 

is run against a project release directory.  These filter values are then written to a config

file in the output directory so the same values can be used on subsequent runs.  

In subsequent runs the filter rules will be loaded from the config file and need not be specified 

on the command line, however the filter rules in the config file can be changed by specifying 

them again on the command line and the config will be re-written.
