appswitch 1.1d2 [unreleased]
===============

A command-line interface to the Mac OS X process manager.

WHAT IS IT?
-----------

If you use shell scripts to automate Mac OS X applications, you may
need to switch between applications.  You could use AppleScript via
osascript(1), but that would take several seconds for the script to
compile and execute - or you could use appswitch, which works almost
instantly.

Say you're launching an X11 application from Terminal but the X server
isn't in front when you need it.  Use appswitch to fix the problem.

Or, if you'd like a version of the ps(1) utility which understands the
concept of OS X applications, appswitch can help.

INSTALLATION
------------

The commands below install the 'appswitch' tool in /usr/local/bin,
which is in the default path.  You should subsequently be able to use
'appswitch' by typing its name.  If you wish to install it somewhere
else, modify the install line as appropriate.

% sudo /usr/bin/install -d /usr/local/bin /usr/local/man/man1
% sudo /usr/bin/install -c build/appswitch /usr/local/bin
% sudo /usr/bin/install -c appswitch.1 /usr/local/man/man1
% rehash                                # if necessary

Uninstallation:

% sudo rm -f /usr/local/bin/appswitch /usr/local/man/man1/appswitch.1

COMPILATION
-----------

An Xcode project, 'appswitch.xcodeproj', is included.  A precompiled
Universal binary is also provided.  'appswitch' should build under
Xcode 2.4 or later.

USAGE
-----

Just type 'appswitch' by itself to receive usage information.  See the
manual page (man appswitch) for more information.

If you're curious about the speed difference between appswitch and
other methods, this should give you some indication.

appswitch -a Emacs          0.01s user 0.01s system 28% cpu 0.069 total
launch -a Emacs             0.01s user 0.01s system 35% cpu 0.076 total
open -a Emacs               0.04s user 0.02s system 52% cpu 0.115 total
osascript -e 'tell application "Emacs" to activate'
                            0.13s user 0.06s system 59% cpu 0.326 total

The above tests were performed on a Mac mini Core Duo 1.66 GHz; slower
systems show more dramatic differences.
