-// This header file defines buffer assignment helper methods to compute correct
-// and valid positions for placing Alloc and Dealloc operations.
+// We use the term "bufferize" to mean conversion from tensor types to
+// memref types.
+//
+// Generally speaking, for each op that operates on tensor types, a conversion
+// pattern needs to be written. The infrastructure in this file assists in
+// defining these conversion patterns in a composable way.
