are built. This commit just moves some man pages to PLIST.v6 and
PLIST.opaquelsa.
No revbump because the package, if it built before, will be unchanged.
But now building with non-default options should work.
via PR #29518 with some slight modifications. Also some review
by Greg Troxel (who is a quagga developer). This is based on the
pkgsrc-wip version.
This has many changes. But ChangeLog is incomplete.
This uses USE_LIBTOOL.
Uses rcd scripts provide from quagga distribution (are pkgsrc/NetBSD style).
Adds USE_ZEBRA_OSPF_OPAQUELSA build definition for --enable-opaque-lsa.
All patches removed.
