But the --summary option seems to generate a different set of license string names (almost as if --from=mixed isn't used (#60)):

$ pip-licenses --summary
 Count  License
 2      Apache 2.0
 1      Apache License 2.0
 1      Apache Software License
 10     BSD
 1      BSD License
 1      BSD-2-Clause or Apache-2.0
 4      BSD-3-Clause
 1      BSD-like
 3      Expat license
 1      LGPL
 18     MIT
 4      MIT License
 2      MIT license
 1      MPL 2.0
 1      MPL-2.0
 1      PSF
 1      Public Domain <http://unlicense.org>
 1      Python license
 1      UNKNOWN
 1      public domain, Python, 2-Clause BSD, GPL 3 (see COPYING.txt)

I would expect pip-licenses --summary to output an aggregated list of licenses using the license string names shown in pip-licenses. This has the advantage that the --from=mixed names are much more uniform, and thus group more nicely.

I opened a PR to fix this issue. See #94
