# Module name   : jats_svnrelease.pl

# Module type   : Jats Utility

# Compiler(s)   : Perl

# Environment(s): Jats

#

# Description   : A script to build a package from a SubVersion

#                 The script will:

#                   Create a workspace

#                   Checkout the files

#                   Locate the build file

#                   Build the packages

#                   Install packages

#                   Remove the view

#

#               The script can do a lot of other things too.

#

# Notes         : A lot of this code is common to jats_ccrelease.pl

#                 Will need to refactor if both are to be used

=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> or B<-spec>

The Subversion label to use as the base for the workspace.

Eg: DPG_SWBASE/daf_utils_math/tags/3.2.1@12345

=item B<-view name>

Specified an alternate view name and tag to be used. This option does not provide the

full name of the view.

    The view path will be: "${USER}_${NAME}"

The default "NAME" is the first label specified with the repository and tag removed.

If the user provides a view "name" that is prefixed with their user name

('${USER}_'), then the username will be stripped of for internal processing.

This allows a user to provide a view path when deleting a view.

=item B<-path=xxx>

Specifies the source path to the root of the extracted file tree. This option is

not mandatory and is only used to mnaintain toolset compatability woth other

,similar, tools.

If provided, then the Workspace will be created within the named subdirectory

tree within the base of the view.

=item B<-build=xxx>

This option allows the user to specify the packages to be built and the

order in which the packages are to be built.

This is useful if the extracted view contains multiple build files

This option may be used multiple times.

There are two forms in which the build target can be specified. It can be

specified as a full package name and vesrion, or as a package name and the

project suffix.

By default the program will assume that there is only one build file in the

view and will not build if multiple files are present, unless the package to be

built can be resolved.

The location mechanism operates for both JATS and ANT build files.

Example: -build=jats-api.1.0.0000.cr

This will locate the build file that builds version 1.0.0000.cr of the jats-api

package. The version numbers must match exactly.

Example: -build=jats-api.cr -build=jats-lib.cr

This will located the build files that build the jats_api (cr) package and the

jats-lib (cr) package. The version of the packages will not be considered.

=item B<-root=xxx>

This option allows the location of the generated view to be specified on the

command line. The environment variable GBE_VIEWBASE provides the same feature,

but it will affect all the view created.

The default location is:

=over 8

=item WINDOWS

c:\clearcase

=item Unix

$(HOME)/jats_cbuilder

If the comamnd is invoked within a development sandbox, then the default

location will be the root directory of the development sandbox.
