38This is the automatically generated usage text for ntpsnmpd.
39
40The text printed is the same whether selected with the @code{help} option
41(@option{--help}) or the @code{more-help} option (@option{--more-help}).  @code{more-help} will print
42the usage text by passing it through a pager program.
43@code{more-help} is disabled on platforms without a working
44@code{fork(2)} function.  The @code{PAGER} environment variable is
45used to select the program, defaulting to @file{more}.  Both will exit
46with a status code of 0.

62                                - may appear multiple times
63
64Options are specified by doubled hyphens and their name or by a single
65hyphen and the flag character.
66
67
68The following option preset mechanisms are supported:
69 - reading file $HOME/.ntprc
70 - reading file ./.ntprc
71 - examining environment variables named NTPSNMPD_*

79@cindex ntpsnmpd-agentxsocket
80
81This is the ``the socket address ntpsnmpd uses to connect to net-snmpd'' option.
82This option takes a string argument.
83[<transport-specifier>:]<transport-address>
84The default "agent X socket" is the Unix Domain socket
85@file{unix:/var/agentx/master}.
86Another common alternative is @file{tcp:localhost:705}.

89@node ntpsnmpd config
90@subsection presetting/configuring ntpsnmpd
91
92Any option that is not marked as @i{not presettable} may be preset by
93loading values from configuration ("rc" or "ini") files, and values from environment variables named @code{NTPSNMPD} and @code{NTPSNMPD_<OPTION_NAME>}.  @code{<OPTION_NAME>} must be one of
94the options listed above in upper case and segmented with underscores.
95The @code{NTPSNMPD} variable will be tokenized and parsed like
96the command line.  The remaining variables are tested for existence and their
97values are treated like option arguments.
98
99
100@noindent
101@code{libopts} will search in 2 places for configuration files:
102@itemize @bullet
103@item
104$HOME
105@item
106$PWD
107@end itemize
108The environment variables @code{HOME}, and @code{PWD}
109are expanded and replaced when @file{ntpsnmpd} runs.
110For any of these that are plain files, they are simply processed.
111For any that are directories, then a file named @file{.ntprc} is searched for
112within that directory and processed.
113
114Configuration files may be in a wide variety of formats.
115The basic format is an option name followed by a value (argument) on the
116same line.  Values may be separated from the option name with a colon,
117equal sign or simply white space.  Values may be continued across multiple
118lines by escaping the newline with a backslash.
119
120Multiple programs may also share the same initialization file.
121Common options are collected at the top, followed by program specific
122segments.  The segments are separated by lines like:
123@example
124[NTPSNMPD]
125@end example
126@noindent
127or by
128@example
129<?program ntpsnmpd>
130@end example
131@noindent
132Do not mix these styles within one configuration file.
133
134Compound values and carefully constructed string values may also be
135specified using XML syntax:
136@example
137<option-name>
138   <sub-opt>...&lt;...&gt;...</sub-opt>
139</option-name>
140@end example
141@noindent
142yielding an @code{option-name.sub-opt} string value of
143@example
144"...<...>..."
145@end example
146@code{AutoOpts} does not track suboptions.  You simply note that it is a
147hierarchicly valued option.  @code{AutoOpts} does provide a means for searching
148the associated name/value pair list (see: optionFindValue).
149
150The command line options relating to configuration and/or usage help are:
151
152@subsubheading version (-)
153
154Print the program version to standard out, optionally with licensing
155information, then exit 0.  The optional argument specifies how much licensing
156detail to provide.  The default is to print just the version.  The licensing information may be selected with an option argument.
157Only the first letter of the argument is examined:
158
159@table @samp
160@item version
161Only print the version.  This is the default.
162@item copyright
163Name the copyright usage licensing terms.
164@item verbose
165Print the full copyright usage licensing terms.

168@node ntpsnmpd exit status

170
171One of the following exit values will be returned:
172@table @samp
173@item 0 (EXIT_SUCCESS)
174Successful program execution.
175@item 1 (EXIT_FAILURE)
176The operation failed or the command syntax was not valid.
177@item 66 (EX_NOINPUT)
178A specified configuration file could not be loaded.
179@item 70 (EX_SOFTWARE)
180libopts had an internal operational error.  Please report
