btcd is a full-node bitcoin implementation written in Go.

The default options are sane for most users.  This means btcd will work 'out of
the box' for most users.  However, there are also a wide variety of flags that
can be used to control it.

The following section provides a usage overview which enumerates the flags.  An
interesting point to note is that the long form of all of these options
(except -C) can be specified in a configuration file that is automatically
parsed when btcd starts up.  By default, the configuration file is located at
~/.btcd/btcd.conf on POSIX-style operating systems and %LOCALAPPDATA%\btcd\btcd.conf
on Windows.  The -C (--configfile) flag, as shown below, can be used to override
this location.

Usage:
  btcd [OPTIONS]
