# This script allows to automatically build and test AspectC++ with multiple clang versions. It produces a compact
# report about AspectC++'s status in terms of supported clang versions.
### Optional arguments ###
# $1 clang_version_array (see below)
# $2 clang_dir_path_prefix (see below)
# $3 build target, i.e., make's TARGET argument
if [ $# -gt 3 ]

# Array of version strings. For each string, the corresponding clang version is used for testing AspectC++. Pre-built
# binaries/libraries can be downloaded from http://releases.llvm.org/download.html.

# Path to directory containing clang binary/library directories plus the prefix of all clang binary/library directory
# names.
# When concatenated with a version from the version array, it must result in a path to the root of a clang
# binary/library directory. From that path, "./bin/llvm-config" should point to llvm-config binary.
# For example, extract all downloaded pre-built binary/library files to your home and rename each extracted root
# directory to llvm-<version>. In this case, clang_dir_path_prefix should be "$HOME/llvm-"
# Note: Please provide absolute paths. Tilde (~) is not supported.
