+ complies with all the legal guidelines:
  + License: GPLv2+ and GFDL, matches actual license
  + No known patent problems
  + No emulator, no firmware, no binary-only or prebuilt components
+ COPYING (GNU GENERAL PUBLIC LICENSE Version 2), COPYING.DOC (GNU Free Documentation License Version 1.2) packaged as %doc

+ builds on at least one arch
  build from mock is in F18 kde-unstable repo
+ no known non-working arches, so no ExcludeArch needed
+ no missing BuildRequires (builds in mock)
+ locales are handled properly by using %find_lang %{name} --with-kde macro
+ ldconfig call not needed (no shared libraries)
+ no duplicated system libraries
+ package not relocatable (no Prefix tag)
+ directory ownership correct (doesn't own directories owned by another package, owns all package-specific directories %{_kde4_appsdir}/%{name}/)
+ no duplicate files in %files
+ permissions correct, %defattr(-,root,root,-) not needed now, executables have executable permissions
+ macros used where possible (%{name}, %{version}, %{buildroot}, %{_target_platform}, %{cmake_kde4}, %{_kde4_datadir}, %{_kde4_bindir}, %{_kde4_iconsdir},%{_kde4_appsdir} )
+ non-code content: only permitted content, themes under license that matches the code
+ no large documentation files, so no -doc package needed
+ no %doc files required at runtime
+ no header files, no -devel package needed
+ no static libraries, so no -static package needed
+ no devel symlinks which would need to be in a -devel subpackage
+ devel packages must require the base package (no -devel package)
+ no .la files
+ knetwalk.desktop file for the GUI app knetwalk present
+ desktop-file-validate is used in %check and the knetwalk.desktop file passes validation
+ all filenames are valid UTF-8
+ other packaging guidelines:
  + complies with the Filesystem Hierarchy Standard (all files in  %{_kde4_datadir}, %{_kde4_bindir}, %{_kde4_iconsdir},%{_kde4_appsdir})
  + proper changelog, tags, BuildRequires, Summary, Description (got from knetwalk's documentation)
  + no non-UTF-8 characters
  + all relevant documentation included as %doc (COPYING, COPYING.DOC)
  + RPM_OPT_FLAGS are used in %{cmake_kde4} macro
  + debuginfo package is valid (contains stripped symbols from ELF binary and source code related to it)
  + no rpaths (no check-rpaths error)
  + no configuration files, so %config guideline doesn't apply
  + no init scripts, so init script guideline doesn't apply
  + timestamps are preserved
  + %{?_smp_mflags} used
  + not a web application, so web application guideline doesn't apply
  + no conflicts (kdegames-4.10.0 is metapackage now which not includes apps)

SHOULD Items:
+ license already included upstream
+ no translations for description and summary provided by upstream
+ package builds in mock (built for kde-unstable)
- successfully tested the package functionality (no testing yet)
+ scriptlets are sane (updating icon chache in %post, %postun, %posttrans)
+ subpackages other than devel should require the base package using a fully versioned dependency (no subpackages)
+ no .pc files, so "placement of .pc files" is irrelevant
+ no file dependencies
- package should contain man pages for binaries/scripts
