=head1 NAME

gen_cots - Create a buildable package from dpkg_archive and place it under

version control

=head1 SYNOPSIS

jats gen_cots package version

 Options:

    -help              - brief help message

    -help -help        - Detailed help message

    -man               - Full documentation

    -label=name        - Specify a label for the versions source

    -vob=vvv           - VOB to use, my be a full path. default is COTS

    -subdir=nnn        - Named subdir in VOB

    -test              - Do not perform any clearcase operations

    -keep              - Keep the creating dpkg_archive image

    -delete            - Unconditional delete the temp directory before use

    -image=path        - Path to alternate source image

=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<-label=name>

This option specifies an alternate label for the checked in source. The

default label is based on package and version.

=item B<-vob=vvv>

This option specifies the VOB into which the saved package will be placed.

There are two ways that this option may be used.

=over 8

=item 1

Simply name the VOB. (ie: COTS) The script will locate a dynamic view on the

users machine that contains the view. This is done by scanning dynic views in

the "O:" drive.

=item 2

The full path to a VOB, including driver is provided. (ie: z:/COTS). This will

prevent the script from locating the VOB. It will use the named view.

=back

If this option is not provided, then the script will use the COTS vob in the

first dynamic view located on the "O:" drive.

=item B<-subdir=name>

This option specifies the name of a subdirectory in which the package will be created.

The default name it taken from the package name.

=item B<-test>

This option will suppress the clearcase operations.

No files will be checked in and the label will not be locked.

=item B<-keep>

If this option is selected then the program will retain the working directory

that it has created.

=item B<-delete>

If this option is selected then the temp work directory will be deleted before

the script attempts to use it.

=item B<-image=path>

If this option is specified then the package will be created using the

specified source path, otherwise the package will be extracted from dpkg_acrhive.

This option allows a locally created image to be stored as a COTS package

before it is placed in dpkg_archive.

=back

=head1 DESCRIPTION

This program will create a version controlled and JATS buildable package from

a dpkg_archive package version.

In doing this the program will:

=over 8

=item   *

Create a temporary directory in the users current directory. This will

be used to contain a copy of the package.

=item   *

Transfer the named package and version into the temp directory. The files will

be transferred in the a 'src' directory within the temp directory.

=item   *

Create JATS build.pl and makefile.pls to support the creation of the

package. The build.pl file will contain the package name and the package

version.

=item   *

Transfer the entire image into the named VOB. The files will be labeled

and the VOB view modified to mimic the temp directory view.

=item   *

Lock the label used to mark the files.

=item   *

Remove the temp work space.

=item   *

Display information to be entered into Release Manager.

=back

=head1 EXAMPLE

jats etool gen_cots -vob=z:/COTS mos_api 5.6.0.cr

This will take the version 5.6.0.cr of the mos_api package from dpkg_acrchive

place it under version control within the COTS vob and add files to allow the

dpkg_archive package to be recreated in an JATS buildable manner.
