=head1 DESCRIPTION

B<gpt-bundle> Creates binary or source bundles from an installation or a
collection of source packages.  These bundles can then distributed be
installed using I<gpt-install> or I<gpt-build>. A bundle consists of a
collection of packages and a XML formatted description file. The DTD
for this file is found in I<$GPT_LOCATION/etc/gpt_bundle.dtd>.

The script accepts a list of packages from the command line or from an
inputed bundle description file.  It expands this list to include all
of the packages that the listed packages depend on. It then uses this
expanded list to create a new bundle description file which is then
added to the collection of packages to form a bundle.

B<gpt-bundle> assumes that all of the packages needed to create a
source bundle are found in one subdirectory identified by the
I<-srcdir> switch.

B<gpt-bundle> assumes that all of the packages need to create a binary
bundle are installed in a location identified by the I<-installdir>
flag or $GLOBUS_LOCATION.

The list of packages that can be entered from the command line are of
the form I<NAME-FLAVOR-PACKAGE_TYPE>.  The wildcard character '*' can
also be used.

=head1 OPTIONS

=over 8

=item B<-srcdir=PATH>

Specifies where the directory containing your source packages is.
If this is used, a source bundle will be created.  Note that this flag
is required to create source bundles.

=item B<-installdir=PATH> 

Specifies where the installation used for creating binary bundles is.
$GLOBUS_LOCATION is the default.

=item B<-xml=FILE> 

Specifies the input bundle description file.  A new file will be
generated using the contents of this file and included in the bundle.

=item B<-bundlename=NAME>

The name of the bundle.  This name is stored in the bundle description
file and used as part of the bundle filename if B<-output> is not
specified.


=item B<-bundleversion=MAJOR.MINOR>

This is the bundle version number.  It is stored in the bundle
description file and used for bundle updates.  It is also used for the
bundle filename if B<-bundlelabel> is not specified.

=item B<-bundlelabel=VERSION>

This is the bundle version label. It is stored in the bundle
description file as a string and so can accomodate any versioning
scheme.  The label is used in user queries, and as part of the bundle
filename.

=item B<-bundlestability=STABILITY>

This is the bundle version stability.  It is a field that is used to
indicate the stability of this version of the bundle.  The field can
have values of B<experimental>, B<alpha>, B<beta>, or B<production>.  The
default vaule is experimental.  The field is stored in the bundle description
file and used for user queries.

=item B<-tmpdir=PATH> 

Specifies the where the directory is that B<gpt-bundle> should use to
store generated binary packages.


=item B<-all>

Tells B<gpt-bundle> to bundle all of the packages in the source
package directory or installation.

=item B<-native>

Tells B<gpt-bundle> to also bundle packages that are in the native
format of the operating system.  Presently this only works for RPMS on
linux.  B<gpt-bundle> will output two bundle giving the native bundle
a platform specific extension such as -rpm.

=item B<-nodeps>

Tells B<gpt-bundle> to only include the packages specified--do not check for or
include dependencies.

=item B<-nosetups>

Tells B<gpt-bundle> to exclude any packages that are pulled in by a
setup dependencies.  Note that setup packages that are listed on the
command line will still be added to the bundle..

=item B<-exclude=package1,package2,...>

This option excludes the listed packages from the created bundle.  It
can be specified multiple times with the final listing used being an
aggregate of all the listed packages.  This option can be abbreviated
as '-exclude=package1,package2,...'.

=item B<-output=FILE>

This is an alternative way to specify the bundle name.  The output
file is put in the directory from which B<gpt-bundle> was invoked if
no path was given, in a directory relative it if a relative path was
given, or in the absolute location, if given.

=item B<-template>

Creates an empty Bundle XML that can be modified and used to create
a new bundle.

=item B<-bundledef=FILE>

Creates an XML file with name equal to B<FILE>.gpt-bundle.xml.  This
file will contain a GPT Bundle definition with values set to those 
passed in on the command line.

=item B<-rpmprefix=<path_to_installation>>

This should be set to the path to your GLOBUS_LOCATION.  GPT will use a
value of "/usr/grid" if this option is not specified.

=item B<-rpmlicense=<label>>

Provides an alternate copyright label for the rpms. The default is
whatever GPT was configured with.

=item B<-help>

Print a brief help message and exits.

=item B<-buildnumber=<number>>

Build number used to version static packages.

=item B<-man>

Prints the manual page and exits.

=item B<-version>

Prints the version of GPT and exits.

=head1 Bundle Definition File Overrides

The I<-bundle*> switches can be used to override content in the bundle
definition file inputted by the I<-xml> switch.  The relationship
between the switches and the bundle definition file contents is shown
in the following table:

  I<Switch>         I<Element>         I<Attribute>

  -bundlename       GPTBundleData      Name
  -bundleversion    BundleReleaseInfo  Major, Minor
  -bundlelabel      BundleReleaseInfo  VersionLabel
  -bundlestability  VersionStability   Release

=head1 Bundle Names and Versions

B<gpt-bundle> encourages a naming convention for bundle filenames.
The convention can be overriden using the I<-output> switch.  The
convention is as follows:

  NAME-VERSION-src_bundle.tar.gz for source bundles
  NAME-VERSION-ARCH-gpt.tar.gz for gpt binary bundles. ARCH is the platform ID.
  NAME-VERSION-ARCH-rpm.tar.gz for rpm binary bundles.

NAME comes from the I<-bundlename> switch.  VERSION comes from the
I<-bundlelabel> switch.  If this switch is not used then VERSION
comes from the I<-bundleversion> switch.

Unless overrided by the switches previously mentioned, the values for
can also be extracted from the bundle definition file inputted by the
I<-xml> switch.
