The as-distributed PDF version of this free textbook has bookmarks do not match the content structure of the document.
I use PDF bookmarks to assist in navigating large documents, especially when using as a reference.
This navigation is especially quick with my usual PDF viewer zathura (https://pwmt.org/projects/zathura/), which is focused on keyboard-centric operation.
The small utility pdf_bookmark.py reads an input file (toc.votl) with bookmark information and uses Ghostscript to add the appropriate additional information.
The file format here is:
(page-number) Bookmark text (page-number) Second-level text 1 (page-number) Third-level text (page-number) Second-level text 2
The votl Vim Outliner Plugin (https://github.com/insanum/votl) is convenient for editing a file with this format.
NOTE: The pdf_bookmark.py here is a modified version of https://github.com/xianghuzhao/pdf-bookmark that accepts the above bookmark format file.
(Less work to modify the code than to port my already-finished file)
totoc.py is my previous, less featureful, script that reads toc.votl and outputs a file suitable for pdftk update_info.
