+#create milestone of basic activities from Siyavula folder
+#source folder has text files a01..a99.txt representing individual activities after conversion from 
+#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)
