#! /bin/bash

# This script is intended to generate a tarball of source code and screenshots,
# 'htdocs_plot_examples.tgz', that will be part of the 'examples' web page,
#
# This script must be run in the top plplot source directory as:
#
#     scripts/htdocs-gen_plot-examples.sh
#
# The tarball will be copied to SourceForge and unpacked at the www area.
# If your user name (as given by the environment variable USER) is different
# as that at SF, then launch the script like this:
#
#     WWW_USER=joeplplotter scripts/htdocs-gen_plot-examples.sh
#
# It is also possible to override the variables WWW_GROUP, WWW_HOST,
# and WWW_DIR in the same way as with WWW_USER in the example above.
#
# To avoid rebuild launch it like this:
#     build=false scripts/htdocs-gen_plot-examples.sh


# a fresh make, with minimum bindings
