   It may not by "fancy" as you may like, but I have been using the following
program to sort variable star names.

   VSNET format to metacodes:
   http://ftp.kusastro.kyoto-u.ac.jp/pub/vsnet/others/prog/DOS/vpre.c
   http://ftp.kusastro.kyoto-u.ac.jp/pub/vsnet/others/prog/DOS/vpre.exe

   Metacodes to VSNET format:
   http://ftp.kusastro.kyoto-u.ac.jp/pub/vsnet/others/prog/DOS/vpost.c
   http://ftp.kusastro.kyoto-u.ac.jp/pub/vsnet/others/prog/DOS/vpost.exe

   Well, they were one of my "first" C codes when I start learning C ;-)

ANDR
ANDRR
ANDAA
ANDV335
CASCEa
CYGV404
CYGV1500
SGRV10000

  will become

!0 
!AR 
!JA 
![00335 
/LEa 
@[00404 
@[01500 
o[10000 

  after processing with vpre

  So, in order to sort,

  vpre <file.org | sort | vpost >file.srt
