# k2pdfopt requires modified versions of mupdf, leptonica, and tesseract.

# However, Debian just uses system versions with minimal fixes to k2pdfopt's

# willuslib; some fixes to mupdf and leptoanica have since been upstreamed,

# some are not relevant on Linux

# Applying the upstream changes to fresh tesseract with our glibc leads to

# k2pdfopt that crashes on launch, so we can drop tesseract or use the old

# version that k2pdfopt wants
