|api|The API server is the core of Arvados. It is backed by a Postgres database and manages information such as metadata for storage, a record of submitted compute jobs, users, groups, and associated permissions.|
|arv-git-httpd|Provides a git+http interface to Arvados-managed git repositories, with permissions and authentication based on an Arvados API token.|
+|arvados-dispatch-cloud|Provide elastic computing by creating and destroying cloud based virtual machines on compute demand.|
|crunch-dispatch-local|Get compute requests submitted to the API server and execute them locally.|
|crunch-dispatch-slurm|Get compute requests submitted to the API server and submit them to slurm.|
|crunch-run|Dispatched by crunch-dispatch, executes a single compute run: setting up a Docker container, running it, and collecting the output.|
|keepstore|Provides access to underlying storage (filesystem or object storage such as Amazon S3 or Azure Blob) with Arvados permissions.|
|keep-web|Provides high-level WebDAV access to collections (file-level data access).|
|login-sync|Synchronize virtual machine users with Arvados users and permissions.|
-|nodemanager|Provide elastic computing by creating and destroying cloud based virtual machines on compute demand.|
-|ws|Publishes API server change events over websockets.|
+|arvados-ws|Publishes API server change events over websockets.|
|workbench|Web application providing user interface to Arvados services.|
h3. Tools
|keep-block-check|Given a list of keep block locators, check that each block exists on one of the configured keepstore servers and verify the block hash.|
|keep-exercise|Benchmarking tool to test throughput and reliability of keepstores under various usage patterns.|
|keep-rsync|Get lists of blocks from two clusters, copy blocks which exist on source cluster but are missing from destination cluster.|
-|sync-groups|Take a CSV file listing (group, username) pairs and synchronize membership in Arvados groups.|
+|sync-groups|Take a CSV file listing with (group, user, permission) records and synchronize membership in Arvados groups.|
