These two are legacy JRE and JDK images.  They are not built by the 
"modules" target.

jre-base-image is the minimal Java runtime only with jdk.boot and 
jdk.base modules installed

jdk-base-image is jre-base-image with the language tools including 
javac, javah, javap, and javadoc.  This is convenience for running tests 
for the base image that needs javac to compile.

Full JDK (equivalent to j2sdk-image)
i.e. jre-module-image + all other jdk modules installed (e.g. all tools, 
debugging, hprof, etc).

The new module images output by the "modules" target are also described 
in jdk/make/common/Modules.gmk.

The modules target also generates jdk modules in:
build/linux-amd64/jigsaw-pkgs/[jmod, deb]
  - all jdk modules are packaged in jmod file format under the jmod 
directory
  - if building on debian systems, debian packages are created under the 
deb directory.

Alan has hacked up a quick tool to generate the javadoc for each of the 
modules.   Before the javadoc becomes module-aware, it would be useful 
to post the per-module javadoc for reference.
