of the Distutils. A useful analogy for command classes is to think of
them as subroutines with local variables called "options". The options
are "declared" in 'initialize_options()' and "defined" (given their
final values, aka "finalized") in 'finalize_options()', both of which
must be defined by every command class. The distinction between the
two is necessary because option values might come from the outside
world (command line, config file, ...), and any options dependent on
other options must be computed *after* these outside influences have
been processed -- hence 'finalize_options()'. The "body" of the
subroutine, where it does all its work based on the values of its
options, is the 'run()' method, which must also be implemented by every
command class.

are just a bunch of "self.foo = None" assignments.

This is always called as late as possible, ie. after any option
assignments from the command-line or from other commands have been
done. Thus, this is the place to code option dependencies: if
'foo' depends on 'bar', then it is safe to set 'foo' from 'bar' as
long as 'foo' still has the same value it was assigned in
'initialize_options()'.

option of the same command. 'src_cmd' is the other command from

'(src_option,dst_option)' tuples which mean "take the value of

more input files and generate one output file. Works just like
'execute()', except the operation is skipped and a different
message printed if 'outfile' already exists and is newer than all
files listed in 'infiles'. If the command defined 'self.force',
and it is true, then the command is unconditionally run -- does no
timestamp checks.
