#################################
# History:
#
# version 22: * JGF: added an option '-m FILE' to hold a CSV speaker map file.
#
# version 21: * JGF: added a flag '-n' to not remove the directory paths from the source
# files in the UEM file.
#
# version 20: * change metadata discard rule: rather than discard if the midpoint
# (or endpoint) of the metadata object lies in a no-eval zone, discard
# if there is ANY overlap whatsoever between the metadata object and
# a no-eval zone. This holds for system output objects only if the
# system output metadata object is not mapped to a ref object.
# * optimize IP and SU mapping by giving a secondary bonus mapping score
# to candidate ref-sys MD map pairs if the end-words of both coincide.
#
# version 19: * bug fix in subroutine speakers_match
# * bug fix in tag_ref_words_with_metadata_info
#
# version 18: * cosmetic fix to error message in eval_condition
# * added conditional output options for word coverage performance
# * added secondary MD word coverage optimization to word alignment
# * further optimize word alignment by considering MD subtypes
# * further optimize MD alignment by considering MD subtypes
# * add a new SU discard rule: discard if TEND in no-eval zone
# * enforce legal values for su_extent_limit
#
# version 17: create_speaker_segs modified to accommodate the same speaker
# having multiple overlapping speaker segments. (This is an
# error and pathological condition, but the system must either
# disallow (abort on) the condition, or perform properly under
# the pathological condition. The second option is chosen.)
#
# version 16: * If neither -w nor -W is specified, suppress warnings about
# ref SPEAKER records subsuming no lexemes.
# * Output the overall speaker diarization stats after the
# stats for the individual files
# * Do not alter the case of alphabetic characters in the filename
# field from the ref rttm file
# * Made the format of the overall speaker error line more similar to
# the corresponding line of output from SpkrSegEval, to facilitate
# use of existing "grep" commands in existing scripts.
#
# version 15: * bug fix in create_speaker_segs to accommodate
# contiguous same-speaker segments
# * added conditional file/channel scoring to
# speaker diarization evaluation
#
# version 14: bug fix in md_score
#
# version 13: add DISCOURSE_RESPONSE as a FILLER subtype
#
# version 12: make REF LEXEMES optional if they aren't required
#
# version 11: change default for noscore MD regions
#
# version 10: bug fix
#
# version 09:
# * avoid crash when metadata discard yields no metadata
# * make evaluated ref_wds sensitive to metadata type
# * defer discarding of system output metadata until after
# metadata mapping, then discard only unmapped events.
# * extend 1-speaker scoring inhibition to metadata
# * eliminate demand for SPKR-INFO subtype for speakers
# * correct ref count of IP and SU exact boundary words
# * add official RT-04F scores
# * add conditional analyses for file/chnl/spkr/gender
#
# version 08:
# * bug fixes speaker diarization scoring
# - count of EVAL_WORDS corrected
# - no-score extended to nearest SPEAKER boundary
#
# version 07:
# * warning issued when discarding metadata events
# that cover LEXEMEs in the evaluation region
#
# version 06:
# * eliminated unused speakers from speaker scoring
# * changed discard algorithm for unannotated SU's and
# complex EDIT's to discard sys SU's and EDIT's when
# their midpoints overlap (rather than ANY overlap).
# * fixed display_metadata_mapping
#
# version 05:
# * upgraded display_metadata_mapping
#
# version 04:
# * diagnostic metadata mapping output added
# * uem_from_rttm bug fix
#
# version 03:
# * adjusted times used for speaker diarization
# * changed usage of max_extend to agree with cookbook
#
# version 02: speaker diarization evaluation added
#
# version 01: a merged version of df-eval-v14 and su-eval-v16
