gophernicus  is  a gopher server. It serves almost compliant RFC 1436, with small changes to make it more
       modern.  gophernicus supports userdirs, executable gophermaps, CGI, and virtual hosting (in the limits of
       the RFC).

       gophernicus can log to syslog(3) or per-server files in Apache format.

       The options are as follows:

       -hhostname     Changes the server hostname shown on the output menu.  The default is the fully qualified
                       domain name of the machine.

       -pport         Changes the server port shown on the output menu.  The default is 70.

       -Tport         Changes the SSL/TLS port.  The default is 0 (disabled).

       -rdirectory    Set the document root of the server.  The default is /var/gopher.

       -ttype         Set the default gopher filetype.  The default is 0.

       -gmapfile      Set the gophermap file name.  The default is gophermap.

       -atagfile      Set the gophertag file name.  The default is gophertag.

       -cdirectory    Set the CGI script directory, under the document root.  The default is /cgi-bin/.

       -udirectory    Set the name of the personal gopherspace directory.  Each  user  can  deploy  a  personal
                       gopherspace  by  creating  a directory directory in their home directory.  The default is
                       public_gopher.

       -lfile         Log to file in Apache-compatible combined format. Disabled by default.

       -wwidth        Set default page width.  The default is 67.

       -ocharset      Select the output charset. It can be UTF-8, US-ASCII,  or  ISO-9959-1.   The  default  is
                       UTF-8.

       -sseconds      Session timeout in seconds.  The default is 1800.

       -ihits         Maximum hits until throttling.  The default is 4069.

       -kkilobytes    Maximum transfer size in KiB until throttling.  The default is 4194304 (4 GiB).

       -fdirectory    Set directory where output filters are found.  Disabled by default.

       -eext=type     Map file extension ext to gopher filetype type.

       -Rold=new      Rewrite the start of a selector.

       -Ddescription  Set  server  description  to  appear  in /caps.txt.  If description looks like a filename
                       (starts with a /), use the contents of the file.

       -Llocation     Set server location to appear in /caps.txt.  If location looks like  a  filename  (starts
                       with a /), use the contents of the file.

       -Aemail        Set the email of the administrator to appear in /caps.txt.

       -Upaths        Set a colon-separated list of extra unveil(2) paths (only for OpenBSD).

       -nv             Disable virtual hosting.

       -nl             Disable parent directory links.

       -nh             Disable menu header.

       -nf             Disable menu footer.

       -nd             Don't show date and size of files in menu.

       -nc             Disable file content detection (similar to magic(5)).

       -no             Disable output charset conversion.

       -nq             Disable HTTP-style query strings ‘?foo=bar&baz=quux’.

       -ns             Disable logging to syslog(3).

       -na             Disable autogenerated /caps.txt.

       -nt             Disable /server-status.

       -nm             Disable shared memory use (for debugging purposes).

       -nr             Disable root user check (for debugging purposes).  By default, gophernicus will refuse to
                       run as root.

       -np             Disable HAProxy proxy protocol.

       -nx             Disable execution of gophermaps and scripts.

       -nH             Disable HTTP response to HTTP GET and POST requests.

       -d              Print debug output in syslog(3) and /server-status.  When -ns (disable syslog(3)) is used
                       this option has no effect.

       -v              Display version information and build date.

       -b              Display licensing information.

       -?              Display help.

       Default values may have been changed at compile time by gophernicus.env.
