Inspiration for XD-build core task description and structure

gistfile1.py

fetch = Task()
fetch.mount('/task/fetch', '%s/%s'%(FETCH_BASEDIR, FETCH_SUBDIR))

unpack = Task()
unpack.after('fetch')
unpack.mount('/task/fetch', '%s/%s'%(FETCH_BASEDIR, FETCH_SUBDIR), ro=True)
unpack.capture('/task/src')

configure = Task()
configure.after('fetch')
def do_configure():
    print('do_configure')
configure = do_configure
configure.capture('/task/build')

compile = Task()
compile.after(['configure'])
def do_compile():
    print('do_compile')
compile = do_compile
compile.capture('/task/build')

install = Task()
install.after('compile')
install.capture('/task/install')

package = Task()
package.after('install')
package.export('/task/package', '%s/%s'%(PACKAGE_BASEDIR, PACKAGE_SUBDIR))
