usage: $0 <options..>

This script creates certificates and sourcable rc files per project/user.

Target account directory hierarchy:
target_dir-|
           |-cacert.pem
           |-project1-name|
           |              |- user1
           |              |- user1-cert.pem
           |              |- user1-pk.pem
           |              |- user2
           |              ..
           |-project2-name..
           ..

Optional Arguments
-P include password to the rc files; with -A it assume all users password is the same
-A try with all user
-u <username> create files just for the specified user
-C <project_name> create user and project, the specifid project will be the user's project
-r <name> when combined with -C and the (-u) user exists it will be the user's project role in the (-C)project (default: Member)
-p <userpass> password for the user
--heat-url <heat_url>
--os-username <username>
--os-password <admin password>
--os-project-name <project_name>
--os-project-id <project_id>
--os-user-domain-id <user_domain_id>
--os-user-domain-name <user_domain_name>
--os-project-domain-id <project_domain_id>
--os-project-domain-name <project_domain_name>
--os-auth-url <auth_url>
--os-cacert <cert file>
--target-dir <target_directory>
--skip-project <project-name>
--debug

Example:
$0 -AP
$0 -P -C myproject -u myuser -p mypass
