+# BEWARE: this script is meant to compile a -personal- SL client. It is -NOT- #
+#         suitable to build client versions meant for public release, because #
+#         non-open source code is packaged by this script.                    #
+###############################################################################
+
+# This bash script is aimed at easying up the build process of a SL client
+# with cmake.
+# You may enable or disable the use of your system's library by editing
+# the USE_SYSTEM_* variable ("yes" --> use the system library, "no" --> use
+# LL's provided ones).
+# The script also takes care of updating properly the viewer_manifest.py script
+# accordingly, so that you (should) end up with a properly packaged client.
+
+# To use this script, simply make it executable (chmod +x cmake-SL) and
+# put it into /usr/local/bin (or any other directory in your PATH).
+# Then, download the slviewer-src-*.tar.gz, slviewer-linux-libs-*.tar.gz,
+# slviewer-artwork-*.zip and fmodapi*.tar.gz archives, and finally, invoke
+# make-SL as follow:
+#   cmake-SL path_to_archives  (example: make-SL ~/downloads)
+# or simply:
+#   cmake-SL
+# when invoking from the directory where the archives are.
+# The sources will be installed into the PATH_TO_SOURCES directory,
+# and the client will be built into the TEMP_DIR directory.
+# The packaged build will be moved to your home directory.
+#
+# If you want to retry a compilation after fixing something manually and
+# don't want cmake-SL to start all over again, overwriting everything,
+# you may invoke it with the --retry option, like this:
+#   cmake-SL --retry
+#
+# Finally, if you just want to prepare the sources without starting the
+# compilation, use:
+#   cmake-SL [path_to_archives] --prep
+#
+# This script has been tested by the author, on (very customized)
+# Mandriva 2007.1 and 2009.0 distros.

+How to build a linux version.
+
+Edit config-SL-source to suit, the one that comes with the viewer
+is the one used to build the linux release.
+
+Run the scripts in order -
+
+0-patch-SL-source
+1-get-libraries-from-SL
+2-trim-libraries-from-SL
+3-compile-SL-source
+
+The patch script should do nothing unless you have setup patches, so you
+can skip it.  The get-libraries script needs a working network
+connection, it fetches pre built libraries.  It also sets up the build. 
+Trim-libraries removes those pre built libraries again if you configured
+things to not use them.  The compile script does the actual work. 
+Usually when making changes, only the compile script needs to be run
+again.
+
+4-package-viewer can be run at a later stage to actually build a tarball
+of the viewer, ready for users to install.
+
+These scripts are based on cmake-SL v1.31 (c)2008-2009 Henri Beauchamp.
+Released under GPL license v2: http://www.gnu.org/licenses/gpl.txt
+Modifications made by David Seikel.
