# This script assumes that the path to this script is something like:

# /somepath/outdir/archdir/hostdir/bindir/traceview
#
# where "somepath" is some pathname (like "/work/android/device/")
#       "outdir"   is a subdirectory (like "out")
#       "archdir"  is a subdirectory (like "linux-x86-release")
#       "hostdir"  is a subdirectory (like "host")
#       "bindir"   is a subdirectory (like "bin")
#
# e.g. /work/android/device/out/linux-x86-release/host/bin/traceview
#
# and that the following directories also exist:
#
# /somepath/outdir/archdir/hostdir/lib/
# /somepath/outdir/archdir/hostdir/framework/
#
# where:
#       "lib", and "framework" are at the same level as "bindir",
#        and are the literal names.

# Set up prog to be the path of this script, including following symlinks,
# and set up progdir to be the fully-qualified pathname of its directory.
