# Changelog:
#
# 2000-01-05 Bj�rn Jacke <bjoern.jacke@gmx.de>
# - first version with translation rules derived from
# metaphone.cc distributed with aspell 0.28.3
# - "TH" is now representated as "@" because "0" is a
# meta character
# - removed TH(!vowel) --> T; always use TH --> # instead
# - dropped "^AE" -> "E" (redundant)
# - "ing" is transformed to "N", not "NK"
# - "SCH(EO)" transforms to "SK" now
# - added R --> SILENT if (after a vowel) and no (vowel or
# "y" follows) like in "Marcy" or "abort"
# - H is SILENT in RH at beginning of words
# - H is SILENT if vowel leads and "Y" follows
# - some ".OUGH.." --> ...F exceptions added
# - "^V" transforms to "W"
