# This perl script both generates the www-browser form and accepts the results |
10 |
# of submitting the form. The search is transmitted to a central machine |
11 |
# and the results are interpreted and reposted for the user. |

13 |
# $Log: Dict,v $ |

20 |
# |
21 |
# Revision 1.9 1998/02/23 16:41:30 hoffman |

23 |
# |
24 |
# Revision 1.8 1998/02/20 16:00:01 hoffman |

# gave the generated page(s) a general facelift, changed internal processing |
26 |
# to use the short database name, not the description, and then spent time |

28 |
# the search and database options have been combined into one. |
