##  Application appname : sources [ : options ]
##    Build an application out of sourcefiles. All sourcefiles will be passed
##    to the Objects rule which tries to compile them into object-files. You
##    can create rules for your own filetypes with the UserObject rule. Header
##    files will just be ignored. They are only used for MSVC projectfile
##    generation.
##    Possible options are "noinstall" if you don't want a default install
##    target to be created and "console" if you're building a console
##    application (an application without any graphical output which is
##    intended to be used on commandline)
##    Some notes: You should not add the .exe extension to the appname - jam
##    will do that on win32.
##    Options:
##	console: Create a console application
##	noinstall: Do not set up a default installation targets.
##	independent: The target will not be made a dependency of the apps and
##		     all target.
##	nohelp: Do not invoke Help for this target.
##      notest: Do not set up unit-testing support for this target.
##	nomanifest: (Win32/MSVC) Don't generate manifest for application.
