Packaging

The *.tar.gz contains a simple and valid *.spec file, the usual rpm maker can simply do

 
  rpm -ta errno-0.2.3.tar.gz 

The package itself is made using autoconf/automake including the usual build sequence:

 
  sh configure --prefix=$HOME && make && make install 

  make doc && make install-doc 

The package does not contain a troff manpage on purpose: when a programmer wants to look up a `man errno` then it is better to present errno(3) which is provided by the system maker. Installing an errno.1 along with this project would make `man errno` to present errno(1) of course which is most probably not what the programmer wants - and worse, some newb programmer might overlook the fact and never read errno(3).

Packagers are therefore advised to not create a troff manpage, even when general policies require that (e.g. debian packages). Simply refuse it, and if you can not stand it, then do atleast just a symlink errno(3) into errno(1) - do not use help2man, pleeeease.
