# PAM authentication library for Linux - Linux-PAM
#
# NOTE: this is a library with plug-in modules, at present all
# the modules are built and installed into the main libpam
# ipkg.  This causes lots of problems (e.g. it is not possible
# to build on uClibC) so *do not* rely on this behaviour -
# assume the modules will be moved to individual ipks (like
# the kernel modules.)
#
DESCRIPTION = "\
PAM authentication library for Linux.  \
Linux-PAM (Pluggable Authentication Modules for Linux) is a \
library that enables the local system administrator to choose \
how individual applications authenticate users. For an \
overview of the Linux-PAM library see the Linux-PAM System \
Administrators' Guide."
