It requires modified versions of mupdf, +# leptonica, and tesseract. Instead of shipping patches for these upstream +# packages, k2pdfopt includes just the modified source files for these +# packages. The individual files from the {mupdf,leptonica,tesseract}_mod/ +# directories are intended to replace the corresponding source files in the +# upstream packages, for a particular version of that upstream package. +# +# There are a few ways we could approach packaging these modified versions of +# mupdf, leptonica, and mupdf: +# 1) Override the upstream source with a new derivation that involves copying +# the modified source files from k2pdfopt and replacing the corresponding +# source files in the upstream packages. Since the files are intended for a +# particular version of the upstream package, this would not allow us to easily +# use updates to those packages in nixpkgs. +# 2) Manually produce patches which can be applied against the upstream +# project, and have the same effect as replacing those files. This is what I +# believe k2pdfopt should do this for us anyway. The benefit of creating and +# applying patches in this way is that minor updates (esp. security fixes) to +# upstream packages might still allow these patches to apply successfully. +# 3) Automatically produce these patches inside a nix derivation.
