# Indent Java code using emacs
# Usage: jindent [-n] [-d]
#    -n Print what would happen, but don't checkout or modify files
#
# The Emacs  CC-mode FAQ says:
#     *Q.* *How do I re-indent the whole file?*
#
#     *A.* Visit the file and hit `C-x h' to mark the whole buffer. Then
#     hit `<ESC> C-\'.
#
# C-x h mark-whole-buffer
# ESC C-\ indent-region
#(fset 'jindent
#   "\C-xh\C-[\C-\\")
