create man page for jgrep The jgrep binary doesn't have a man page. The project's README file has some good information about options and expressions and statements accepted by the binary, so we can reuse that information. . This patch creates a man page for the binary that will get compiled with the rules file.
the spec_helper file uses a relative path to load from lib/ autopkgtest is failing since one file in the spec/ directory, spec_helper.rb, is loading the jgrep code with a relative directory from lib. During the CI job, the lib/ directory is not present anymore and thus the tests fail. The spec_helper file should require the code without the relative path.
