.SH DESCRIPTION
.
The
.B query-runlisp-config
program assists with understanding and debugging
.BR runlisp.conf (5)
files.
.
.SS "Options"
The command-line options are as follows.
.
.TP
.BR "\-h" ", " "\-\-help"
Write a synopsis of
.BR query-runlisp-config 's
command-line syntax
and a description of the command-line options
to standard output
and immediately exit with status 0.
.
.TP
.BR "\-V" ", " "\-\-version"
Write
.BR query-runlisp-config 's
version number
to standard output
and immediately exit with status 0.
.
.TP
.BR "\-L" ", " "\-\-list-sections"
List all of the known section names to standard output.
.
.TP
.BI "\-c" "\fR, " "\-\-config-file=" conf
Read configuration from
.IR conf .
If
.I conf
is a directory, then all of the files within
whose names end with
.RB ` .conf ',
are loaded, in ascending lexicographical order;
otherwise,
.I conf
is opened as a file.
All of the files are expected to as described in
.BR runlisp.conf (5).
.
.TP
.BI "\-l" "\fR, " "\-\-list-variables=" sect
List all of the variables assigned in section
.I sect
to standard output.
.
.TP
.BI "\-o" "\fR, " "\-\-set-option=\fR[" sect :\fR] var = value
Assign
.I value
to the variable
.I var
in configuration section
.IR sect ,
or
.B @CONFIG
if no section is specified.
The value is unexpandable,
and overrides any similarly named setting
from the configuration file(s).
.
.TP
.BI "\-p" "\fR, " "\-\-print-variable=\fR[" sect :\fR] var
Print the raw (unexpanded) result of looking up the variable
.I var
in configuration section
.I sect
(defaulting to
.BR @CONFIG ).
.
.TP
.BR "\-q" ", " "\-\-quiet"
Don't print warning messages.
This option may be repeated:
each use reduces verbosity by one step,

which prints only warning measages.
.
.TP
.BR "\-v" ", " "\-\-verbose"
Print informational or debugging messages.
This option may be repeated:
each use increases verbosity by one step,
counteracting one
.RB ` \-q '
option.

which prints only warning measages.
Higher verbosity levels print informational and debugging messages.
.
.TP
.BI "\-w" "\fR, " "\-\-split-variable=\fR[" sect :\fR] var
Print the result of looking up, expanding, and word-splitting the variable
