Constraint on package name #32
Description
There's constraint on package name mentioned in conda-build docs. Should we add it to the JSON schema?
Conda package names are normalized and they may contain only lowercase alpha characters, numeric digits, underscores, hyphens, or dots. In usage documentation, these are referred to by package_name.
