This library should be backwardly compatible with all 2.4 and 2.6
Linux kernels.

Over libcap-1.*, this library adds support for filesystem capabilities
and also 64-bit capabilities. The library also contains a pam_cap
module, for granting inheritable capabilities to users (in the
credential-setting phase of authentication).

Unlike earlier versions of libcap-1, for convenience, this release
contains a verbatim copy of the include/linux/capability.h
file. Before compiling the library, take a moment to check that this
version is the same or newer than that of the kernel du jour.

Earlier versions of libcap have been maintained via sourceforge, but
CVS is less interesting to me now, so I've also created a git repository
for libcap:

  git clone git://git.kernel.org/pub/scm/libs/libcap/libcap.git/

The sources for earlier releases of libcap are there, and also a
libcap2 branch that contains support for capabilities that matches
the top of trunk in the above linux-2.6-fcaps tree (and the mm kernels).
