%% @doc Cloud9
%%
%% Cloud9 is a collection of tools that you can use to code, build, run,
%% test, debug, and release software in the cloud.
%%
%% For more information about Cloud9, see the Cloud9 User Guide.
%%
%% Cloud9 supports these operations:
%%
%% <ul> <li> `CreateEnvironmentEC2': Creates an Cloud9 development
%% environment, launches an Amazon EC2 instance, and then connects from the
%% instance to the environment.
%%
%% </li> <li> `CreateEnvironmentMembership': Adds an environment member
%% to an environment.
%%
%% </li> <li> `DeleteEnvironment': Deletes an environment. If an Amazon
%% EC2 instance is connected to the environment, also terminates the
%% instance.
%%
%% </li> <li> `DeleteEnvironmentMembership': Deletes an environment
%% member from an environment.
%%
%% </li> <li> `DescribeEnvironmentMemberships': Gets information about
%% environment members for an environment.
%%
%% </li> <li> `DescribeEnvironments': Gets information about
%% environments.
%%
%% </li> <li> `DescribeEnvironmentStatus': Gets status information for an
%% environment.
%%
%% </li> <li> `ListEnvironments': Gets a list of environment identifiers.
%%
%% </li> <li> `ListTagsForResource': Gets the tags for an environment.
%%
%% </li> <li> `TagResource': Adds tags to an environment.
%%
%% </li> <li> `UntagResource': Removes tags from an environment.
%%
%% </li> <li> `UpdateEnvironment': Changes the settings of an existing
%% environment.
%%
%% </li> <li> `UpdateEnvironmentMembership': Changes the settings of an
%% existing environment member for an environment.
%%
%% </li> </ul>
