+
+Mandatory Dependencies

+Both python-magic and python-libarchive-c must be built with python3

+
+  PYTHON3=yes ./python-magic.SlackBuild
+  PYTHON3=yes ./python-libarchive-c.SlackBuild
+
+
+Optional Dependencies
+
+argcomplete  (for argument completion)
+colord       (for comparing images)
+colordiff    (for comparing images)
+fontforge    (for comparing font files)
+fpc          (for Pascal support)

+.SH DESCRIPTION
+.sp
+diffoscope will try to get to the bottom of what makes files or
+directories different. It will recursively unpack archives of many kinds
+and transform various binary formats into more human readable form to
+compare them. It can compare two tarballs, ISO images, or PDF just as
+easily.
+.sp
+It can be scripted through error codes, and a report can be produced
+with the detected differences. The report can be text or HTML.
+When no type of report has been selected, diffoscope defaults
+to write a text report on the standard output.
+.sp
+diffoscope is developed as part of the “reproducible builds” Debian
+project and was formerly known as “debbindiff”.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
