# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        dropbox-client
# Descr:      store, sync and share files online
# URL:        http://www.getdropbox.com/
# Needs:      
# Changelog:  
# 0.6.1-1:    08/Oct/2009 by Eric Hameleers <alien@slackware.com>
#             * Initial build. Repackaging a binary RPM and removing the
#               dependency on nautilus (i.e. gnome).
#               Note: this is just the client. Running this will automatically
#               download and start your personal dropbox daemon.
#               This package does not need nautilus to be installed, but in
#               case you do have gnome, the package will integrate into the
#               nautilus.
# 0.6.2-1:    02/jun/2010 by Eric Hameleers <alien@slackware.com>
#             * Updated.
# 0.6.3-1:    22/jul/2010 by Eric Hameleers <alien@slackware.com>
#             * Updated.
# 0.6.7-1:    18/dec/2010 by Eric Hameleers <alien@slackware.com>
#             * Updated. Also fix the fake nautilus script to filter out the
#               "--no-desktop" argument passed by dropbox to the real nautilus.
# 1.4.0-1:    14/oct/2012 by Eric Hameleers <alien@slackware.com>
#             * Updated.
# 1.6.0-1:    03/feb/2013 by Eric Hameleers <alien@slackware.com>
#             * Updated.
# 1.6.1-1:    16/jan/2014 by Eric Hameleers <alien@slackware.com>
#             * Updated.
# 
# Run 'sh dropbox-client.SlackBuild' to build a Slackware package.
# The package (.tgz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'.
