Comment (by mf2k):

 A few comments:
  - As mentioned above, change the name to be "eric". It will require that
 {{{master_sites}}} be slightly modified.
  - It looks like it supports python 3. Please change the python
 dependencies to use py36.
  - The {{{revision}}} line should be deleted because it starts at 0 when
 increasing the version and that is the default value.
  - Any building should happen in the build phase, not the destroot phase.
 So just move the install command there.
  - Sort the dependencies by name.
