#
# For each scripting language liblldb supports, we need to create the
# appropriate Script Bridge wrapper classes for that language so that
# users can call Script Bridge functions from within the script interpreter.
#
# We use SWIG to create a C++ file containing the appropriate wrapper classes
# and funcitons for each scripting language, before liblldb is built (thus
# the C++ file can be compiled into liblldb.  In some cases, additional work
# may need to be done after liblldb has been compiled, to make the scripting
# language stuff fully functional.  Any such post-processing is handled through
# the shell scripts called here.

# SRC_ROOT is the root of the lldb source tree.
# TARGET_DIR is where the lldb framework/shared library gets put.
# CONFIG_BUILD_DIR is where the build-swig-Python-LLDB.sh  shell script
#           put the lldb.py file it generated from running SWIG.
# PREFIX is the root directory used to determine where third-party modules
#         for scripting languages should be installed.
# debug_flag (optional) determines whether or not this script outputs
#           additional information when running.
