Well, it seems that all that "shareware", "$8" and "download demo
version" stuff scared me off initially ;-).

The following came to mind when looking at the spec file to get it

--- 8< ---

> %define version 0.1.4
> %define release 1

Don't do that here, just set name, version, release below (Name:,
Version:, Release:), the macros get set anyway.

Usually the package name shouldn't be repeated in the summary, but I
guess in this instance it is the shortest way to describe it,
unfortunately most people won't know what a tesseract is (I didn't until

See above.

Using "Copyright: ..." is deprecated, use "License: ...".

For Fedora, that would be "Amusements/Games".

Unnecessary, this is set implicitely.

What's missing here are the BuildRequires.

You should elaborate who is keen here, remember people may see only the
description alone. "I" in this context can be the upstream author but
also the packager.

Don't do that here...(*)

IIUC, this option is a noop so "%configure" alone should suffice...(**)

(**)... but you can achieve what you want albeit a bit more cleanly like this:

CXXFLAGS="$(echo %optflags | sed 's/-fomit-frame-pointer//g')" \

Ensure that you "BuildRequire: sed" above.

(*)... but rather here.

(***)... rather include these two files as source files and install them
in %install.

No need to have an empty %postun.
