DESCRIPTION="A network programming library in C++"
HOMEPAGE="http://alumnit.ca/wiki/?WvStreams"
SRC_URI="https://wvstreams.googlecode.com/files/${P}.tar.gz"

LICENSE="GPL-2"

KEYWORDS="alpha amd64 hppa ppc sparc x86"
IUSE="pam doc +ssl +dbus debug boost"

#Tests fail if openssl is not compiled with -DPURIFY. Gentoo's isn't. FAIL!
RESTRICT="test"

#QA Fail: xplc is compiled as a part of wvstreams.
#It'll take a larger patching effort to get it extracted, since upstream integrated it
#more tightly this time. Probably for the better since upstream xplc seems dead.
