# This expects to find a file pam-*.txz in the local directory that
# will contain a usable PAM shared library to satify the requirement
# for that library.  To get whatever is actually using PAM working is
# going to need more PAM structure installed, but luckily I've yet to
# encounter what needs it and everything works fine with only the
# libpam.so.0 installed.

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

google-chrome-pam-solibs: google-chrome-pam-solibs (libpam.so.0)
google-chrome-pam-solibs:
google-chrome-pam-solibs: This is a package that provides libpam.so.0 to satisfy the library
google-chrome-pam-solibs: requirement for Google Chrome when that is installed in the
google-chrome-pam-solibs: usual /opt/google/chrome directory.  It does not provide any other
google-chrome-pam-solibs: PAM features, and cannot be used to compile against or by other
google-chrome-pam-solibs: programs.  If you need real PAM for some reason (like to compile
google-chrome-pam-solibs: Chromium), please see the pam.SlackBuild in the source directory.
