- Move sgml2latex to separate subpackage, avoid pulling in half
of TeXLive when e.g. only sgml2html is required.
- Really remove sgmltool-flex.patch, was only applied for obsolete
distribution versions.
- Stop distributing RTF and LyX versions of the guide; plaintext,
HTML and Postscript should be sufficient.
- spec file cleanup:
* drop defattr, use license, use buildroot instead of shell variable
* remove long obsolete distro support
