There he worked on gcc, g++, libio (the precursor to GNU/Linux stdio), gdb, Kawa, and more. Later he worked in the Java group at Sun and Oracle. Per wrote the Emacs term mode. Currently, Per spends too much time on Kawa (a Scheme compiler and framework for the Java platform), and DomTerm (a terminal emulator based on web technologies).
