# Example on how to use the Image::Kimdaba.pm module
# to parse & update the image database made by the beautiful
# Kimdaba available on http://ktown.kde.org/kimdaba
# Copy paste from this to start your own script.
#
# To use it, run $ kimdaba -demo, 
# or launch the demo from the Kimdaba help menu
# and run it as
#	./kim_example_modifyb.pl /tmp/kimdaba-demo-$user
# (or whereever the pictures of the demo are stored )

# This example shows how to make change in the database
# Instead of modifying directly the database (which could easily be dangerous
# for your data), you write a kimdaba export file (*.kim)
# then you use the import fonction in kimdaba (no dangerous, you are in control)
#
# A .kim file is a zip archive containning an index.xml file, and
# a Thumbnail directory. You just have to create the index.xml file 
# (say in '/tmp') then you call :
#
#   makeKimFile( "/tmp", "perl_output.kim", @ListOfPictures );
# where /tmp/index.xml is the file created by you
#	/tmp/perl_output.kim	is the resulting kimdaba import ile
#	@ListOfPictures		is a list of urls present in /tmp/index.xml
