# rpmbuild spec file for pdnsd.
# with modifications by Paul Rombouts.

# Supported rpmbuild --define and --with options include:
#
# --with isdn                   Configure with --enable-isdn.
#
# --without poll                Configure with --disable-poll 
#
# --without nptl                Configure with --with-thread-lib=linuxthreads.
#
# --with ipv6                   Configure with --enable-ipv6.
#
# --without tcpqueries          Configure with --disable-tcp-queries.
#
# --without debug 	        Configure with --with-debug=0.
#
# --define "distro <distro>" 	Configure with --with-distribution=<distro>.
#
# --define "run_as_user <user>" Configure with --with-default-id=<user>.
#                               For RPMs the default <user> is "pdnsd".
#
# --define "run_as_uid <uid>" 	If the user defined by the previous option does not exist
#                               when the RPM is installed, the pre-install script will try
#                               to create a new user with numerical id <uid>.
#
# --define "cachedir <dir>" 	Configure with --with-cachedir=<dir>.

%description
pdnsd is a proxy DNS daemon with permanent (disk-)cache and the ability
to serve local records. It is designed to detect network outages or hangups
and to prevent DNS-dependent applications like Netscape Navigator from hanging.

The original author of pdnsd is Thomas Moestl, but pdnsd is no longer maintained
by him. This is an extensively revised version by Paul A. Rombouts.
For a description of the changes see http://www.phys.uu.nl/~rombouts/pdnsd.html
and the file README.par in %{_docdir}/%{name}-%{version}

%{!?distro:You can specify the target distribution when you build the source RPM. For instance, if you're building for a Red Hat system call rpmbuild with:}
%{!?distro:  --define "distro RedHat"}
%{?distro:This package was built for a %{distro} distribution.}
%{!?_with_isdn:It's possible to rebuild the source RPM with isdn support using the rpmbuild option:}
%{!?_with_isdn:  --with isdn}
%{?_with_isdn:This package was built with isdn support enabled.}
%{!?_with_ipv6:It's possible to rebuild the source RPM with ipv6 support using the rpmbuild option:}
%{!?_with_ipv6:  --with ipv6}
%{?_with_ipv6:This package was built with ipv6 support.}
%{?_without_poll:This package was built with the select(2) function instead of poll(2).}
