Version 0.07 31-Mar-96
  1) Added the ArticleHeader search pattern.  This will allowing extracting 
     articles with "protected" headers.
  2) Added MustUseArticleHeader option.
  3) Added option to process digests in SOUP packets and to add the extracted
     articles to the same SOUP packet.
  4) Added capability to process "unix mailbox", "unix MMDF mailbox", and 
     "R-News" folder formats.
  5) Added "debug" option to test configuration files without creating an 
     output file or modifing the SOUP packet.
  6) Added code to determine a folder type by it's contents.
  7) Changed output error levels.  Now shows if a digest was found in addition
     to showing errors.
  8) Changed the generation of Message-IDs to be based on the location within 
     the digest instead of the location within the packet.  This may prevent
     duplication of some messages if the digest is imported twice from two
     different packets.
  9) Added a test to see if a Message-Id: header is already included in the
     article being extracted.  If so, one will not be added.

Version 0.06 23-may-95
  1) Added Text input.
  2) Added option for piped input and output.
  3) Fixed bug in finding messages with empty lines at the start.
  4) Changed () (grouping) construct to more closely match POSIX.  
     Previously, the regular expression in the parentheses would match
     the longest string at the expense of the entire expression.
  5) Added '\s' and '\e' constructs to regular expressions (set start 
     and end of match).

        regular characters inside []'s, except for [: :] classes.
     d) Added () (grouping) construct.
     e) Added | (or) operator.
  2) Fixed bug in parsing command line when using "-Y" (Yarn folder) 
     option.  Options may now be placed anywhere on the command line.
