Any of the command-line options mentioned above can be specified in a
configuration file instead. We first look for \(dqhtsnrc\(dq in the

+.P
+The user's home directory is simply $HOME on Unix; on Windows its
+wherever %APPDATA% points. The system configuration directory is
+determined by Cabal; the \(dqsysconfdir\(dq parameter during the
+\(dqconfigure\(dq step is used.

The file's syntax is given by examples in the htsnrc.example file
(included with \fBhtsn\fR).
