Conversion of areatags to newsgroups (with distribution) and back.

 Lines starting with a whitespace are comments.  This is because
 areatags may contain a hash ('#') character which would otherwise
 be sutable as a comment designator.

 AREATAG   newsgroup   distribution   modtype:moderator

 If you compile with -DJE, the format is:
 AREATAG  newsgroup   distribution   rfc-charset  FTN-CHRS   modtype:moderator

 "rfc-charset" is the charset used in the rfc (usenet/email) side. It must
 be in the format used in MIME headers (ex: iso-8859-1, koi8-r, EUC-kr,...)
 "FTN-CHRS" is the charset used in the FTN side. It must be in the format
 used in ^aCHRS: kludges, whitout de level number (ex: LATIN-1, KOI8, EUC-KR)
 See file README.charset for a list of recognized rfc-charset and FTN-CHRS

 "moderator" is an rfc address of the moderator.
 "modtype" is either "umod","fro" or "fstd".
 umod stands for usenet moderated, messages arriving in a pkt are converted
      to email for the defined moderator.
 fro  stands for fido read-only; when the gated area is defined as (Moderated)
      it create correct "Approved:" lines.
 fstd stands for fido standart way of moderation, (does nothing yet)

 exemple (with -DJE):

 COMERZ  fido.commerz world iso-8859-1 CP437 fro:Jan.Smith@f1.n2.z3.fidonet.org

 You have to write here the tag conversions, probably one by one.

 An international area
NET_DEV               fido.int.net_dev
 An italian area
RC&REC_NEWS.033       fido.ita.033.rc&rec_news
 Etc...

  Line with a single '*' in the "newsgroup" field defines default areatag.
  '*' in the "AREA" field, if present, is expanded to the original
  newsgroup (converted to uppercase).  (Distribution is insignificant).
 
  If you define it, an FTN message will be generated for each newsgroup in
  the Newsgroups: header, even if you're not linked to it, and an ECHO doesn't
  really exist for it. Is better not to define.

  U_*                     *
 
  Line with a single '*' in the "AREA" field defines default newsgroup
  and distribution.  '*' in the "newsgroup" field, if present, is expanded
  to the original areatag (converted to lowcase).

*                       fido.*                  	#fido

  You can specify a line with a single asterisk in the "AREA" field and
  a single asterisk in the "newsgroup" field.  It will cause a reversible
  conversion - areatag will be an uppercased newsgroup, and a newsgroup 
  will be a lowercased areatag.  This is not recommended.
