 # This build deals with 3 kinds of objects
-# 
+#
 # (*) packages are named upon the RPM name; they are mostly lowercase
 #     Add a package to ALL if you want it built as part of the default set.
-# (*) modules are named after the subversion tree; as of this writing their names 
-#     are mostly mixed case like MyPLC or VserverReference
-#     (this is something we'll fix while moving to git)
+# (*) modules are named after the subversion or git tree; we would wish to keep
+#     these names lowercase as far as possible
 # (*) rpms are named in the spec files. A package typically defines several rpms;
-#     rpms are used for defining DEPEND-DEVEL-RPMS. See also package.rpmnames
-# 
+#     rpms are used for defining LOCAL-DEVEL-RPMS. See also package.rpmnames
+#
+# in simple cases, one package uses one module (in which case using the same name sounds right)
+# but others might need several modules (e.g. image-creation packages like bootstrapfs need
+# bootstrapfs and build); in this case the FIRST ONE is used for locating the specfile

-# (*) package-DEPEND-DEVEL-RPMS
-#     a set of *rpms* that the build will rpm-install before building <package>
+#     a set of (obviously local) *packages* that this package depends on, e.g.

+#     a set of stock rpms that this package needs at build-time

+# (*) package-LOCAL-DEVEL-RPMS
+#     a set of *local* rpms that the build will rpm-install before building <package>
 #     the build will attempt to uninstall those once the package is built, this is not fatal though
 #     this is intended to denote local rpms, i.e. ones that are results of our own build

+#     like package-LOCAL-DEVEL-RPMS but for crucial packages (like autoconf) that only need an update from our build
+#     rpms in this area will *not* be uninstalled after the target is made, because that would ruin the build vm for good

+#     see automatic below
 # (*) package-RPMFLAGS: Miscellaneous RPM flags
-# (*) package-RPMBUILD: If not rpmbuild - mostly used for sudo'ing rpmbuild
-# (*) package-BUILD-FROM-SRPM: set this to any non-empty value, if your package is able to produce 
-#     a source rpms by running 'make srpm'
+#     this is passed to rpmbuild, as well as to spec2make for "exporting" various rpm variable
