Alternatively, one can use the autounmask command, for example:

    autounmask dev-java/eclipse-ecj-3.5.1

On my AMD64 system, which has /etc/portage/package.keywords (as a
directory, rather than a file) autounmask generated file:

    /etc/portage/package.keywords/autounmask-eclipse-ecj

which contains:

   # ---
   # BEGIN: dev-java/eclipse-ecj-3.5.1
   # ---
   =dev-java/eclipse-ecj-3.5.1 ~amd64
   =dev-java/ant-eclipse-ecj-3.5.1 ~amd64
   # ---
   # END: dev-java/eclipse-ecj-3.5.1
   # ---
