Arguments:
NAME name of the cloud
Options:
-h --help show this help message and exit
-v --version show version and exit
-f NAME --file=NAME the Name of the cloud to be specified,
if ? a selection is presented
-o OUT --out=OUT writes the result in the specifide file
-p PROJECT --project=PROJECT selects a project (e.g. for eucalyptus
which has project-specific environments)
-u USER --user=USER the user (login) name
-r HOST --remote=HOST the host machine on which the yaml file is
located in the CONFIG directory

-d --debug debug
- this option is a - at the end of the command.
If data is written to a file it is also put out to stdout
Description:
Command to generate rc files from our cloudmesh configuration files.
This program generates form a YAML file containing the login
information for a cloud an rc file that can be used to later source
it.
Example:
we assume the yaml file has an entry india-openstack::
cm-manage config -o novarc india-openstack
source novarc
This will create a novarc file and than you can source it::
cm-manage config ? -
Presents a selction of cloud choices and writes the choice into a
file called CONFIG/novarc
