| At the bottom of the file is where the real magic happens, "BuildPackage" is a macro setup by the earlier include statements. BuildPackage only takes one argument directly -- the name of the package to be built, in this case "bridge". All other information is taken from the define blocks. This is a way of providing a level of verbosity, it's inherently clear what the DESCRIPTION variable in Package/bridge is, which wouldn't be the case if we passed this information directly as the Nth argument to BuildPackage. | At the bottom of the file is where the real magic happens, "BuildPackage" is a macro setup by the earlier include statements.
