The conditions are as follows:

```

    * Redistributions of source code must retain the above copyright notice,
      this list of conditions and the following disclaimer.

    * Redistributions in binary form must reproduce the above copyright notice,
      this list of conditions and the following disclaimer in the documentation
      and/or other materials provided with the distribution.

    * Redistributions in any form must be accompanied by information on how to
      obtain complete source code for the software that uses SVNKit and any
      accompanying software that uses the software that uses SVNKit. The source
      code must either be included in the distribution or be available for no
      more than the cost of distribution plus a nominal fee, and must be freely
      redistributable under reasonable conditions. For an executable file, complete
      source code means the source code for all modules it contains. It does not
      include source code for modules or files that typically accompany the major
      components of the operating system on which the executable file runs.

    * Redistribution in any form without redistributing source code for software
      that uses SVNKit is possible only when such redistribution is explictly permitted
      by TMate Software. Please, contact TMate Software at support@svnkit.com to
      get such permission.
```

in particular, the 3rd statements mandates source code disclosure in case of code / software distribution.
