Computes a build plan. This means figuring out which build Task
s to take,
and the interdependencies among the build Task
s. In particular:
1) It determines which packages need to be built, based on the transitive
deps of the current targets. For local packages, this is indicated by the
lpWanted
boolean. For extra packages to build, this comes from the
extraToBuild0
argument of type Set PackageName
. These are usually
packages that have been specified on the command line.
2) It will only rebuild an upstream package if it isn't present in the
InstalledMap
, or if some of its dependencies have changed.
3) It will only rebuild a local package if its files are dirty or some of its dependencies have changed.
