#doc format. Folder also has all of the images for the milestone.
#
#for each folder in SOURCE create a milestone folder in TARGET
#for each a*.txt file in SOURCE folder create an activity folder in TARGET / milestone
#also add an entry in activities.js
#copy the a*.txt file to the activity folder as source.txt
#for each image tag in a*.txt, replace the tag with a comment <!--In_imgn.png height xxx width xxx left-->
#copy the source image to the activity folder renaming it imgn (where n is the number of the image in this activity)
