conda creating environments. Parameter choice

Question

The documentation for conda has the following example:

$ conda create -n py33 python=3.3 anaconda

My question is, why do we specify anaconda as an argument here? (what other options are available and what are the differences)?

Is anaconda here a meta-package? If so, what other metapackages are available?

Answer 1

According to the help, anaconda in that example installs the package spec anaconda.
