" * the keywords are listed by file (sqlnet.ora, listener.ora, etc.)
" * the parathesis-checking is made at the beginning for all keywords
" * possible values are listed also
" * there are some overlappings (e.g. METHOD is mentioned both for
"   sqlnet-ora and tnsnames.ora; since will not cause(?) problems
"   is easier to follow separately each file's keywords)

" Remove any old syntax stuff hanging around, if needed
