=head1 NAME
iphoto - a command line shell for iPhoto
=head1 SYNOPSIS
# start the shell
% iphoto
# run a single command
% iphoto merge album1 album2
=head1 DESCRIPTION
THIS IS EXPERIMENTAL SOFTWARE! USE AT YOUR OWN RISK!
This script provides a shell for iPhoto. Make a backup of your photo
library, or use a test library, to play with this script.
=head1 COMMANDS
These commands interact with iPhoto, and some of them will change your
iPhoto library, including deleting photos forever.
The "show" command makes iPhoto display something, while the "print"
command makes the shell display something. For instance, "show boat"
will tell iPhoto to display the album "boat" just as if you had selected
it from iPhoto's albums pane. The command "print albums" will print on
the terminal (not the printer!) the list of albums.
Although some photos may disappear from albums or the photo library, they
are simply in the Trash library, and you do not delete them until you use
the "empty" command. However, since I am still developing this script,
I have disabled that command. You can still use the command, but it
will not empty the trash. To enable the "empty" command, find the
"empty_trash" subroutine and modify the source according to the comment
in the subroutine.
=over 4
=item debug
turn on extra output
=item empty
empty the trash (you cannot recover these photos).
=item help
display available commands
=item make ALBUM_NAME
make an album named ALBUM_NAME
=item merge ALBUM1 ALBUM2
move everything from ALBUM2 to ALBUM1, and remove ALBUM2
=item move ALBUM
move the selected photos to ALBUM
=item quit
stop the shell
=item print [ album | albums | photo | photos | selection ]
Rrint information about the specified object. What these actually
print changes everytime I look at the source, so you have to try
them to see.
=item remove ALBUM
Remove the album. The photos stay in the photo library.
=item show ALBUM
Tell iPhoto to display ALBUM
=item trash
Put the selected photos in the trash
=item version
Print the shell version
=item view [ import | organize | edit | book ]
Change the view. The default is "organize", and using any unknown
view changes it to "organize".
=back
=head1 SOURCE AVAILABILITY
This source is part of a SourceForge project which always has the
latest sources in CVS, as well as all of the previous releases.
http://sourceforge.net/projects/brian-d-foy/
If, for some reason, I disappear from the world, one of the other
members of the project can shepherd this module appropriately.
