# The aim of this script is to collect some traces from oaisim stack and generate a sequence diagram image (png or jpeg).
# Actually it is a let's say a pre alpha release.
# an example of how it can be invoqued: msc_gen.py /tmp/msc_log.txt msc_log.txt is the input text file,
# it is generated by the execution of the oaisim stack: oaisim -...(misc args) | grep MSC_ > msc_log.txt
# Note L.G. to help: I put in script start_one_eNB_multi_UE_nas:
# $OPENAIR_TARGETS/SIMU/USER/oaisim -a -C1 -u $1 | tee /tmp/oai_log.txt | grep MSC_ > /tmp/msc_log.txt
# Now, examples of a mscgen trace in oaisim look like this:
# LOG_D(RRC, "[MSC_NEW][FRAME 00000][RRC_UE][MOD %02d][]\n", Mod_id+NB_eNB_INST); for declaring a new instance of a protocol
#
# LOG_D(RLC, "[MSC_MSG][FRAME %05d][RLC_AM][MOD %02d][RB %02d][--- MAC_DATA_REQ/ %d TB(s) --->][MAC_%s][MOD %02d][]\n", ....)
# for tracing a message between 2 protocol entities on the sequence diagram chart.
#
# LOG_D(RRC, "[MSC_NBOX][FRAME %05d][RRC_UE][MOD %02d][][Tx RRCConnectionReconfigurationComplete to ENB index %d][RRC_UE][MOD %02d][]\n", ...)
# for generating a notice box on the protocol entity sequence diagram chart.
