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.

options that depend on some other command rather than another
option of the same command. 'src_cmd' is the other command from
which option values will be taken (a command object will be created
for it if necessary); the remaining arguments are
'(src_option,dst_option)' tuples which mean "take the value of
'src_option' in the 'src_cmd' command object, and copy it to
'dst_option' in the current command object".
