+.SH CONFIGURATION
+
+All configuration settings may be overriden both by environment variables, or by overriding settings with the contents of ini-files in the directory defined by the \\fB-c\\fP option.
+
+The active configuration, with values assigned from environment and arguments, can be output using the \\fB--dumpconfig\\fP \\fIformat\\fP option. Note that entries having keys prefixed with underscore (e.g. _SEQ) are not actual configuration settings, and thus cannot be overridden with environment variables.
+
+To refer to a configuration setting by environment variables, the \\fIsection\\fP and \\fIkey\\fP are concatenated together with an underscore, and transformed to upper-case. For example, the configuration variable \\fIFOO_BAZ_BAR\\fP refers to an ini-file entry as follows:
+
+.EX
+[foo]
+bar_baz = xyzzy
+.EE
+
+In the \\fBENVIRONMENT\\fP section below, the relevant configuration settings for this tool is listed along with a short description of its meaning.
+
+Some configuration settings may also be overriden by command line options. Also note that the use of the \\fB-n\\fP and \\fB--env-prefix\\fP options affect how environment and configuration is read. The effects of options on how configuration settings are affective is described in the respective \\fBOPTIONS\\fP section.
