# This script is a refactored version of the legacy power scripts (e.g.,
# poweron-vm-default). It expects to be installed in their places --
# in other words, `basename "$0"` might be poweron-vm-default.
#
# Handy reference/shorthand used in this doc/scripts:
# TOOLS_CONFDIR ::= Depends on platform and installation settings. Likely
# "/etc/vmware-tools" or
# "/Library/Application Support/VMware Tools"
# powerOp ::= One of "poweron-vm", "poweroff-vm", "suspend-vm", and
# "resume-vm".
# vmwScriptDir ::= $TOOLS_CONFDIR/scripts/vmware
# userScriptDir ::= $TOOLS_CONFDIR/scripts/${powerOp}-default.d
#
# End users may install scripts of their own under $userScriptDir. They
# are executed in alphabetical order with "$powerOp" as the only argument.
#
# NB: This directory layout remains to preserve backwards compatibility. End
# users are free to write a single script which uses its only parameter
# (${powerOp}) as a discriminator, and then install symlinks to it in each
# of the ${powerOp}-default.d directories.
#
# On power-on and resume, VMware's scripts execute before the end user's. On
# suspend and power-off, the end user's execute before VMware's. (This way,
# VMware stops services only after the user's scripts have finished their
# work, and conversely restores the same services before the user's scripts
# attempt to use them.)
#
# Should any script exit non-zero, only its value will be saved to exitCode.
# (Any further non-zero exits will have no effect on exitCode.) This script
# exits with $exitCode.
#
# XXX Consider using the available/enabled pattern for VMware's scripts.
#
# XXX This should be staged as a single executable whereby the desired
# power operation is passed in as a parameter. (I.e., one would run
# "/path/to/statechange.sh suspend-vm" rather than having to install
# statechange.sh as suspend-vm-default.)
