38 .SH "DESCRIPTION"
39 .
40 The
41 .B tripe-keys.master
42 or
43 .B tripe-keys.conf
44 file is a simple line-based configuration file read by
45 .BR tripe-keys (1).
46 Lines may be empty (consist only of whitespace), be comments (first
47 non-whitespace character is
48 .RB ` # ')
49 or have the form
50 .IP
51 .I name
52 .RB [ = ]
53 .I value
54 .PP
55 A
56 .I name
57 consists of alphanumeric characters and hyphens. Values may contain
58 substitutions, of the form
59 .BI ${ name } \fR,
60 which are replaced by the value assigned to
61 .IR name .
62 Many
63 .IR name s
64 have significance to the
65 .B tripe-keys
66 program: these are described below. Many have sensible defaults.
67 .SS "The tripe-keys.master file"
68 The client configuration file is built by applying substitutions to the
69 .B tripe-keys.master
70 file. The following tokens are substituted:
71 .TP
72 .B @MASTER-SEQUENCE@
73 The sequence number of the most recently-added signing key.
74 .TP
75 .B @HK-MASTER@
76 The fingerprint of the signing key identified by
77 .BR @MASTER-SEQUENCE@ .
78 .SS "Master repository parameters"
79 .TP
80 .I base-url
81 The base URL of the key repository (usually with a trailing
82 .RB ` / ').

96 portion, if any, is replaced by the sequence number of the key which
97 made the signature.
98 .TP
99 .I repos-url
100 The URL for the key repository tarball. Default is the concatenation of
101 .I base-url
102 and

114 default. Usually set up automatically.

129 set up automatically.

131 .I upload-hook
132 A shell command to run by

134 after it has successfully written the
135 .I repos-file
136 and
137 .IR sig-file s.
