# DESCRIPTION: The main scram program (NOTE: this is wrapped at runtime to  #
#              set up the path to the SCRAM Perl modules).                  #
#                                                                           #

# V1.36:       V0_19_3 release ready  Wed Feb 20 13:41:56 2002              #
# V1.39:       NR fixes included (no references to "which" anywhere)        #
# V1.44:       Added -f options to set/project. Added simple parser to      #
#              remove duplicate lib entries.                                #

# 
# o added new command "set"

#
# template generator to create tool template/ bootstrapfile template

This allows other users to refer to a centrally installed project by
this label rather than a remote url reference.

Usage:

project_tag : override default label (the project name of the current release)
version_tag : the version tag of the current release. If version is not

Allows installation/re-installation of a new tool/external package into an 
already existing development area. If no toolname is specified,

Usage:

        $bold scram setup [-i] [-f cmstools.conf] $normal [toolname] [[version] [url]]

toolname : The name of the tool setup file required.
version  : where more than one version exists, specify the version.
url      : when setting up a completely new tool specify the url too.

The -i option turns off the automatic search mechanism allowing for more
user interaction with the setup mechanism.

The -f option allows the user to supply a valid path to a cmstools file (the filename
MUST end in ".conf")

Setup a new project development area. The new area will appear in the current 
working directory.
Usage:

 $bold scram project [-d install_area] [-n directory_name]$normal project_url [project_version] [-f cmstools.conf] 

Options:

project_url: The url of a scram bootstrap file.
   
             Currently supported types are:
   
                $bold Database label $normal
                        Labels can be assigned to bootstrap files for easy
                        access (See "scram install" command). If you
                        specify a label you must also specify a project_version.
                        e.g.

                           scram project ORCA ORCA_1_1_1

                        To see the list of installed projects use the
                        "scram list" command.

                $bold file: $normal A regular file on an accessible file system
                        e.g.

                           file:~/myprojects/projecta/config/BootStrapFile

                              
             Use the "-f" flag followed by a valid filename (which MUST end in ".conf") to
             allow auto setup to proceed without reading files from a repository (standalone mode). 

                
project_version:
                 Only for use with a database label.

-d install_area:
                 Indicate a project installation area into which the new
                 project area should appear. Default is the current working
                 directory.

-n directory_name:
                 Specify the name of the SCRAM development area you wish to 
                 create.
