 * May make sense to provide generic support in libbutl since will probably
   be used in other places (e.g., subprojects globbing).
+
+* Maybe globbing should be an eval context function, e.g.,
+
+  (*.cxx -foo.cxx)
+
+  If relative is it always performed in src? BTW, if out == src then we
+  may end up finding extra stuff.
+
+* The prerequisite idea does not fit well for directories: They are out while
+  we need to search in src. Also, we need to include the buildfiles.
+
+  d = (*/ -build/)
+  ./: $d
+  include $d
+
+  Another option would be to add some magic to directory handling. Sure would
+  be nice to just write:
+
+  ./: {*/ -build/}
+
+  I think we can have a reasonable model for prerequisite search (it is target
+  type-specific). Include will be harder.
