    .Sh DESCRIPTION
    .Nm
    is a version control system which prioritizes ease of use and simplicity
    over flexibility.
    .Pp
    .Nm
    stores the history of tracked files in a repository which uses
    the same on-disk format as
    .Dq bare
    repositories used by the Git version control system.
    This repository format is described in
    .Xr git-repository 5 .
    .Pp
    .Nm
    is a
    .Em distributed
    version control system because every copy of a repository is writeable.
    Modifications made to files can be synchronized between repositories
    at any time.
    .Pp
    Files managed by
    .Nm
    must be checked out from the repository for modification.
    Checked out files are stored in a
    .Em work tree
    which can be placed at an arbitrary directory in the filesystem hierarchy.
    The on-disk format of a
    .Nm
    work tree is described in
    .Xr got-worktree 5 .
    .Pp
    .Nm
    provides global and command-specific options.
    Global options must preceed the command name, and are as follows:
    .Bl -tag -width tenletters
    .It Fl h
    Display usage information.
    .El
    .Pp
    The commands for
    .Nm
    are as follows:
    .Bl -tag -width checkout
    .It Cm checkout [ Fl p Ar path-prefix ] repository-path [ work-tree-path ]
    Copy files from a repository into a new work tree.
    If the
    .Ar work tree path
    is not specified, either use the base name of the
    .Ar repository path ,
    or if a
    .Ar path prefix
    was specified use the base name of the
    .Ar path prefix .
    .Pp
    The options for
    .Cm got checkout
    are as follows:
    .Bl -tag -width Ds
    .It Fl p Ar path-prefix
    Restrict the work tree to a subset of the repository's tree hierarchy.
    Only files beneath the specified
    .Ar path-prefix
    will be checked out.
    .El
    .\".It Cm status
    .\"Show current status of files.
    .It Cm log [ Fl c Ar commit ] [ Fl f ] [ Fl l Ar N ] [ Fl p ] [ Fl r Ar repository-path ] [ path ]
    Display history of a repository.
    If a
    .Ar path
    is specified, show only commits which modified this path.
    .Pp
    The options for
    .Cm got log
    are as follows:
    .Bl -tag -width Ds
    .It Fl c Ar commit
    Start traversing history at the specified
    .Ar commit .
    The expected argument is the name of a branch or a SHA1 hash which corresponds
    to a commit object.
    .It Fl f
    Restrict history traversal to the first parent of each commit.
    This shows the linear history of the current branch only.
    Merge commits which affected the current branch will be shown but
    individual commits which originated on other branches will be omitted.
    .It Fl l Ar N
    Limit history traversal to a given number of commits.
    .It Fl p
    Display the patch of modifications made in each commit.
    .It Fl r Ar repository-path
    Use the repository at the specified path.
    If not specified, assume the repository is located at or above the current
    working directory.
    .El
    .It Cm diff [ Ar repository-path ] Ar object1 Ar object2
    Display the differences between two objects in the repository.
    Each
    .Ar object
    argument is a SHA1 hash which corresponds to the object.
    Both objects must be of the same type (blobs, trees, or commits).
    If the
    .Ar repository path
    is omitted, use the current working directory.
    .It Cm blame [ Fl c Ar commit ] [ Fl r Ar repository-path ] Ar path
    Display line-by-line history of a file at the specified path.
    .Pp
    The options for
    .Cm got blame
    are as follows:
    .Bl -tag -width Ds
    .It Fl c Ar commit
    Start traversing history at the specified
    .Ar commit .
    The expected argument is the name of a branch or a SHA1 hash which corresponds
    to a commit object.
    .It Fl r Ar repository-path
    Use the repository at the specified path.
    If not specified, assume the repository is located at or above the current
    working directory.
