[vz-dev] vzlogger install script

[Andreas Goetz]

Hallo Zusammen,

ich hab mal versucht ein Skript zu bauen das vzlogger installiert oder-
sofern schon vorhanden- aktualisiert. Wäre schön wenn das jemand testen
könnte bevor ich es im git einstelle (@Udo: das wäre auch was für Dich ;)

Viele Grüße,
Andreas

# The installer will clone all required repositories or update them if
necessary.
# Then the modules are compiled and installed
#
# USAGE:
#
#   Run install.sh from vzlogger or parent folder
#
#       ./install.sh
#
#   To execute specific parts of the build select which ones to run:
#
#       ./install.sh <list of modules>
#
#   Modules:
#     - vzlogger (libraries must be in place already)
#     - libjson
#     - libsml
#     - clean (will clean the respektive make targets, requires explicitly
naming the modules)
#
#     To run a clean build:
#
#       ./install.sh vzlogger libjson libsml clean
