       Scalar is a repository management tool that optimizes Git for use in
       large repositories. Scalar improves performance by configuring advanced
       Git settings, maintaining repositories in the background, and helping
       to reduce data sent across the network.

       An important Scalar concept is the enlistment: this is the top-level
       directory of the project. It usually contains the subdirectory src/
       which is a Git worktree. This encourages the separation between tracked
       files (inside src/) and untracked files, such as build artifacts
       (outside src/). When registering an existing Git worktree with Scalar
       whose name is not src, the enlistment will be identical to the

       The scalar command implements various subcommands, and different
       options depending on the subcommand. With the exception of clone, list
       and reconfigure --all, all subcommands expect to be run in an

       The following options can be specified before the subcommand:

       -C <directory>
           Before running the subcommand, change the working directory. This
           option imitates the same option of git(1).

       -c <key>=<value>
           For the duration of running the specified subcommand, configure
           this setting. This option imitates the same option of git(1).


       clone [<options>] <url> [<enlistment>]
           Clones the specified repository, similar to git-clone(1). By
           default, only commit and tree objects are cloned. Once finished,
           the worktree is located at <enlistment>/src.

           The sparse-checkout feature is enabled (except when run with
           --full-clone) and the only files present are those in the top-level
           directory. Use git sparse-checkout set to expand the set of
           directories you want to see, or git sparse-checkout disable to
           expand to all files (see git-sparse-checkout(1) for more details).
           You can explore the subdirectories outside your sparse-checkout by
           using git ls-tree HEAD[:<directory>].

       -b <name>, --branch <name>
           Instead of checking out the branch pointed to by the cloned
           repository's HEAD, check out the <name> branch instead.

           Clone only the history leading to the tip of a single branch,
           either specified by the --branch option or the primary branch
           remote's HEAD points at.

           Further fetches into the resulting repository will only update the
           remote-tracking branch for the branch this option was used for the
           initial cloning. If the HEAD at the remote did not point at any
           branch when --single-branch clone was made, no remote-tracking
           branch is created.

           By default, scalar clone places the cloned repository within a
           <entlistment>/src directory. Use --no-src to place the cloned
           repository directly in the <enlistment> directory.

           A sparse-checkout is initialized by default. This behavior can be
           turned off via --full-clone.

           List enlistments that are currently registered by Scalar. This
           subcommand does not need to be run inside an enlistment.

       register [<enlistment>]
           Adds the enlistment's repository to the list of registered
           repositories and starts background maintenance. If <enlistment> is
           not provided, then the enlistment associated with the current
           working directory is registered.

           Note: when this subcommand is called in a worktree that is called
           src/, its parent directory is considered to be the Scalar
           enlistment. If the worktree is not called src/, it itself will be
           considered to be the Scalar enlistment.

       unregister [<enlistment>]
           Remove the specified repository from the list of repositories
           registered with Scalar and stop the scheduled background

       scalar run ( all | config | commit-graph | fetch | loose-objects |
       pack-files ) [<enlistment>]
           Run the given maintenance task (or all tasks, if all was
           specified). Except for all and config, this subcommand simply hands
           off to git-maintenance(1) (mapping fetch to prefetch and pack-files
           to incremental-repack).

           These tasks are run automatically as part of the scheduled
           maintenance, as soon as the repository is registered with Scalar.
           It should therefore not be necessary to run this subcommand

           The config task is specific to Scalar and configures all those
           opinionated default settings that make Git work more efficiently
           with large repositories. As this task is run as part of scalar
           clone automatically, explicit invocations of this task are rarely

       After a Scalar upgrade, or when the configuration of a Scalar
       enlistment was somehow corrupted or changed by mistake, this subcommand
       allows to reconfigure the enlistment.

       With the --all option, all enlistments currently registered with Scalar
       will be reconfigured. Use this option after each Scalar upgrade.

       diagnose [<enlistment>]
           When reporting issues with Scalar, it is often helpful to provide
           the information gathered by this command, including logs and
           certain statistics describing the data shape of the current

           The output of this command is a .zip file that is written into a
           directory adjacent to the worktree in the src directory.

       delete <enlistment>
           This subcommand lets you delete an existing Scalar enlistment from
           your local file system, unregistering the repository.
