28 .Sh DESCRIPTION
29 .Nm
30 is a version control system which prioritizes ease of use and simplicity
31 over flexibility.
32 .Pp
33 .Nm
34 stores the history of tracked files in a repository which uses
35 the same on-disk format as
36 .Dq bare
37 repositories used by the Git version control system.
38 This repository format is described in
39 .Xr got-repository 5 .
40 .Pp
41 .Nm
42 is a
43 .Em distributed
44 version control system because every copy of a repository is writeable.
45 Modifications made to files can be synchronized between repositories
46 at any time.
47 .Pp
48 Files managed by
49 .Nm
50 must be checked out from the repository for modification.
51 Checked out files are stored in a
52 .Em work tree
53 which can be placed at an arbitrary directory in the filesystem hierarchy.
54 The on-disk format of a
55 .Nm
56 work tree is described in
57 .Xr got-worktree 5 .
58 .Pp
59 .Nm
60 provides global and command-specific options.
61 Global options must preceed the command name, and are as follows:
62 .Bl -tag -width tenletters
63 .It Fl h
64 Display usage information.
65 .El
66 .Pp
67 The commands for
68 .Nm
69 are as follows:
70 .Bl -tag -width checkout
71 .It Cm checkout [ Fl p Ar path-prefix ] repository-path [ work-tree-path ]
72 Copy files from a repository into a new work tree.
73 If the
74 .Ar work tree path
75 is not specified, either use the base name of the
76 .Ar repository path ,
77 or if a
78 .Ar path prefix
79 was specified use the base name of the
80 .Ar path prefix .
81 .Pp
82 The options for
83 .Cm got checkout
84 are as follows:
85 .Bl -tag -width Ds
86 .It Fl p Ar path-prefix
87 Restrict the work tree to a subset of the repository's tree hierarchy.
88 Only files beneath the specified
89 .Ar path-prefix
90 will be checked out.
91 .El
92 .\".It Cm status
93 .\"Show current status of files.
94 .It Cm log [ Fl c Ar commit ] [ Fl f ] [ Fl l Ar N ] [ Fl p ] [ Ar repository-path ]
95 Display history of a repository.
96 If the
97 .Ar repository path
98 is omitted, assume the repository is located in the current working directory.
99 .Pp
100 The options for
101 .Cm got log
102 are as follows:
103 .Bl -tag -width Ds
104 .It Fl c Ar commit
105 Start traversing history at the specified
106 .Ar commit .
107 The expected argument is the name of a branch or a SHA1 hash which corresponds
108 to a commit object.
109 .It Fl f
110 Restrict history traversal to the first parent of each commit.
111 This shows the linear history of the current branch only.
112 Merge commits which affected the current branch will be shown but
113 individual commits which originated on other branches will be omitted.
114 .It Fl l Ar N
115 Limit history traversal to a given number of commits.
116 .It Fl p
117 Display the patch of modifications made in each commit.
118 .El
119 .It Cm diff [ Ar repository-path ] Ar object1 Ar object2
120 Display the differences between two objects in the repository.
121 Each
122 .Ar object
123 argument is a SHA1 hash which corresponds to the object.
124 Both objects must be of the same type (blobs, trees, or commits).
125 If the
126 .Ar repository path
127 is omitted, use the current working directory.
