This copy of Calc is linked against the GNU Readline library. Normally, Calc
is distributed under the LGPL, and for this copy, section 3 of the LGPL has
been applied:

      3. You may opt to apply the terms of the ordinary GNU General Public
    License instead of this License to a given copy of the Library. To do
    this, you must alter all the notices that refer to this License, so that
    they refer to the ordinary GNU General Public License, version 2,
    instead of to this License. (If a newer version than version 2 of the
    ordinary GNU General Public License has appeared, then you can specify
    that version instead if you wish.) Do not make any other change in these
    notices.

Thus, this copy and all subsequent copies and derivative works are under the
terms of the GNU General Public License version 2.

The original "COPYING" document distributed with calc has been removed, as
it is not licensed in a way which permits the changes necessary to make this
conversion. You can find the relevant information in the source RPM or on
the web site at <http://isthe.com/chongo/tech/comp/calc/calc-download.html>.

NOTE: This is intended as a short-term fix; hopefully in the future the
command-line program and the calc libraries will be split in a way that
makes this unnecessary.
