You may (against our preference) also use the Ruby 1.8 license terms which we inherited from the original Mongrel project when we forked it:

### Ruby 1.8-specific terms (if you're not using the GPL)¶ ↑

    1. You may make and give away verbatim copies of the source form of the
       software without restriction, provided that you duplicate all of the
       original copyright notices and associated disclaimers.

    2. You may modify your copy of the software in any way, provided that
       you do at least ONE of the following:

         a) place your modifications in the Public Domain or otherwise make them
         Freely Available, such as by posting said modifications to Usenet or an
         equivalent medium, or by allowing the author to include your
         modifications in the software.

         b) use the modified software only within your corporation or
            organization.

         c) rename any non-standard executables so the names do not conflict with
         standard executables, which must also be provided.

         d) make other distribution arrangements with the author.

    3. You may distribute the software in object code or executable
       form, provided that you do at least ONE of the following:

         a) distribute the executables and library files of the software,
         together with instructions (in the manual page or equivalent) on where
         to get the original distribution.

         b) accompany the distribution with the machine-readable source of the
         software.

         c) give non-standard executables non-standard names, with
            instructions on where to get the original software distribution.

         d) make other distribution arrangements with the author.

    4. You may modify and include the part of the software into any other
       software (possibly commercial).  But some files in the distribution
       are not written by the author, so that they are not under this terms.

    5. The scripts and library files supplied as input to or produced as
       output from the software do not automatically fall under the
       copyright of the software, but belong to whomever generated them,
       and may be sold commercially, and may be aggregated with this
       software.

    6. THIS SOFTWARE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
       IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
       WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
       PURPOSE.
