$ pip install pdfbookmarker

Turn to your target PDF (e.g. MyBook.pdf), record bookmark titles and page numbers of the PDF into a TEXT file (e.g. my_bookmarks.txt) by hand with the following format:
```
<nested level>"<bookmark title>"|<page number>
```
For samples, see sample_bookmarks.txt. (Offsets are also supported, see here)
Generate a copy of MyBook.pdf with additional bookmarks file specified by my_bookmarks.txt:
```
$ pdfbm MyBook.pdf my_bookmarks.txt
```
An auto-detected, expected or suggested filename for bookmarks is MyBook.txt, when the input filenamne e.g. is MyBook.pdf.

```
$ pdfbm MyBook.pdf my_bookmarks.txt MyBook_with_bookmarks.pdf
```
