=head1 DESCRIPTION
-This program makes it easier to boot NOVA or other operating system
-(OS) on different targets (machines or emulators). It reads a so
-called novaboot script, that specifies the boot configuration, and
-setups the target to boot that configuration. Setting up the target
-means to generate the bootloader configuration files, deploy the
-binaries and other needed files to proper locations, perhaps on a
-remote boot server and reset the target. Then, target's serial output
-is redirected to standard output if that is possible.
-
-A typical way of using novaboot is to make the novaboot script
+This program makes booting of an operating system (e.g. NOVA or Linux)
+as simple as running a local program. It facilitates booting on local
+or remote hosts or in emulators such as qemu. Novaboot operation is
+controlled by command line options and by a so called novaboot script,
+which can be thought as a generalization of bootloader configuration
+files (see L</"NOVABOOT SCRIPT SYNTAX">). Based on this input,
+novaboot setups everything for the target host to boot the desired
+configuration, i.e. it generates the bootloader configuration file in
+the proper format, deploy the binaries and other needed files to
+required locations, perhaps on a remote boot server and reset the
+target host. Finally, target host's serial output is redirected to
+standard output if that is possible.
+
+Typical way of using novaboot is to make the novaboot script
executable and set its first line to I<#!/usr/bin/env novaboot>. Then,
booting a particular OS configuration becomes the same as executing a
local program - the novaboot script.
Run an OS in Qemu. This is the default action when no other action is
specified by command line switches. Thus running C<novaboot ./script>
(or C<./script> as described above) will run Qemu and make it boot the
-configuration specified in the I<script>.

-
-Strip I<rom://> prefix from command lines and generated config files.

=head2 File generation phase
In this phase, files needed for booting are generated in a so called
-I<build directory> (see TODO). In most cases configuration for a
-bootloader is generated automatically by novaboot. It is also possible
-to generate other files using I<heredoc> or I<"<"> syntax in novaboot
-scripts. Finally, binaries can be generated in this phases by running
-C<scons> or C<make>.

=item -g, --grub[=I<filename>]
=item --no-file-gen
-Do not generate files on the fly (i.e. "<" syntax) except for the
-files generated via "<<WORD" syntax.
+Do not run external commands to generate files (i.e. "<" syntax and
+C<run> keyword). This switch does not influence generation of files

=item -p, --pulsar[=mac]
Runs C<scons> to build files that are not generated by novaboot
itself.
+=item --strip-rom
+
+Strip I<rom://> prefix from command lines and generated config files.
+The I<rom://> prefix is used by NUL. For NRE, it has to be stripped.
+
=item --gen-only

+=item --amt=I<"[user[:password]@]host[:port]>
+
+Use Intel AMT technology to control the target machine. WS management
+is used to powercycle it and Serial-Over-Lan (SOL) for input/output.
+The hostname or (IP address) is given by the I<host> parameter. If
+I<password> is not specified, environment variable AMT_PASSWORD is
+used. The I<port> specifies a TCP port for SOL. If not specified, the
+default is 16992. Default I<user> is admin.

-Example:
+Lines starting with C<run> keyword contain shell commands that are run
+during file generation phase. This is the same as the "< CMD" syntax
+for C<load> keyboard except that the command's output is not
+redirected to a file. The ordering of commands is the same as they
+appear in the novaboot script.
+
+Example (Linux):
+
+ #!/usr/bin/env novaboot
+ load bzImage console=ttyS0,115200
+ run make -C buildroot
+ load rootfs.cpio < gen_cpio buildroot/images/rootfs.cpio "myapp->/etc/init.d/S99myapp"
+
+Example (NOVA User Land - NUL):
+
#!/usr/bin/env novaboot
