+The Example Processing Files are...
+
+Toplevel...
+   generate_all      - accept some flags and run all "generate" scripts
+                       using those flags 
+   generate_options  - convert command line flags into shell options to
+                       control image generation.  Also provides the
+                       'usage' output
+   index.html
+   generate          - generate script for just the top level
+                       also contains specific index creation for the
+                       four 'image' stores
+
+Each Sub-Directory  (crop is a good general section to study)
+   index.html
+   generate          - generate for each sub-direcory all very simular
+                         * process command line options
+                         * clear/backup existing examples
+                         * link/copy source images into current directory
+                         * generate examples from "index.html"
+                         * run any other scripts needed
+                         * compare examples against backup
+                         * and finally do any special cleanup!
+   generate_*        - other generation scripts need for this section
+
+Processing Scripts (toplevel)
+   generate_clear    - either deletes all image files, or backs them up
+                       for compares. Backup images are prefexed with '_'
+   generate_examples - THE MAIN WORKHORSE
+                       This is the one that reads the HTML index files,
+                       extracts the commands
+                       from 'CODE' blocks.  It then runs the command
+                       according to command line flags, or flags in each
+                       'CODE'
+   generate_compare  - compare backed up images against the just
+                       generated images to find examples where the
+                       results have changed. 
+                       Backups are deleted (or not) after comparison
+   generate_font_chars   - extract specific characters from of array of
+                       an array of characters (for append/montage examples)
+   generate_symbols  - extract images from specific fonts, usually used
+                       to display mathematical processing (morphology)
+   generate_tags     - generate a "tags" index file for vim editor
+                       (you can ignore)
+   generate_version  - create a image of the current IM version during the
+                       example creation of a specific "index.html"
+
+Helper Scripts
+
+   cmp_backups       - look at backup images that was left behind as
+                       they fails the image compare.  I manually
+                       deletes the backup images when satisfied all is
+                       okay.
+   forum_link.cgi    - redirect links to the User Forums appropriately.
+                       The user forum moved three times during those 10
+                       years, and I got sick of having to change all the
+                       links in all the index.html, so I have it go thru
+                       this script.
+
+
+The scripts sub-directory is just scripts for processing images using
+imagemagick.  Many are referred to and even used by specific examples.
+The directory should be in your PATH.
+
+Note in any specific section (sub-directory) I typically tried to keep
+what source images are used to a minimum.
+
+I preferred to reuse the source image in multiple examples,
+or use previously generated example results for later example input.
