 `-d <Directory>`::
   Specify where to place generated .class files. If not specified,
   <Directory> defaults to the current working dir.
-`-target <[1.1 to 1.5]>`::
-  Specify classfile target setting (1.1 to 1.5, default is 1.2)
-`-1.3`::
-  Set compliance level to 1.3 This implies -source 1.3 and -target 1.1.
-`-1.4`::
-  Set compliance level to 1.4 (default) This implies -source 1.4 and
-  -target 1.2.
-`-1.5`::
-  Set compliance level to 1.5. This implies -source 1.5 and -target 1.5.
-`-source <[1.3|1.4|1.5]>`::
-  Toggle assertions (1.3, 1.4, or 1.5 - default is 1.4). When using
-  -source 1.3, an assert() statement valid under Java 1.4 will result in
-  a compiler error. When using -source 1.4, treat `assert` as a keyword
-  and implement assertions according to the 1.4 language spec. When
-  using -source 1.5, Java 5 language features are permitted.

+  Set source file Java language level

+  Set classfile Java bytecode level
+`-<[1.3 to 21]>`::
+  Set compiler compliance level. Implies identical `-source` and `-target` levels.
+  E.g., `-11` implies `-source 11` and `-target 11`.

 `-nowarn`::
   Emit no warnings (equivalent to '-warn:none') This does not suppress
