# Provide a shared terminal window to a running emacs session.
# All scripts can be found at:
#
# http://zwizwa.be/darcs/bin/session
#
#
# This uses:
#
# - session
#
#   A wrapper script around dtach.  Can be found at
#   http://zwizwa.be/darcs/bin/session
#
# - s.emacs
#
#   Outer wrapper.  This is what you use to attach to a session.
#
# - s.emacs.start
#
#   This script.  Start emacsclient in detach.  The reason we're using
#   dtach as an intermediate is that we don't just want a shared emacs
#   session (just emacsclient would be enough) but also want identical
#   screens.
#
# - s.emacs.resize
#
#   Use xtermcontrol to resize the PTY in which emacsclient runs.
#   This PTY is provided by dtach -- it's not your private PTY.  Check
#   that xterm has resize access enabled.  If not, add the following
#   lines to ~/.Xdefaults
#
#     xterm*allowWindowOps: true
#     xterm*allowTitleOps: true
#     xterm*allowFontOps: true
#
#   and refresh using: xrdb ~/.Xdefaults
