+pdfpages - count the pages of a PDF
+
+This was made by AI. I know neither C++ nor Poppler's API. This is the script
+I use to get a list of PDFs with their page count.
+
+ #!/bin/sh -e
+
+ cd "$HOME/data/books"
+ for f in *.pdf; do
+ pdfpages "$f" >> page-count.txt.tmp
+ done
+
+ sort -V page-count.txt.tmp > page-count.txt
+ rm page-count.txt.tmp
+
+The difference is only a few tenths of a second when using pdfinfo instead of this program.
+
+ #!/bin/sh -e
+
+ cd "$HOME/data/books"
+ for f in *.pdf; do
+ pages="$(pdfinfo "$f" | grep Pages)"
+ pages="${pages##* }"
+ echo "$pages: $f" >> page-count.txt.tmp
+ done
+
+ sort -V page-count.txt.tmp > page-count.txt
+ rm page-count.txt.tmp
