#

# 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.)
