Series2 performs a series expansion around 0. Series2 is (up to the Gamma - bug) equivalent to Series, except that it applies Normal on the result and has an option FinalSubstitutions. Series2[f, e, n] is equivalent to Series2[f, {e, 0, n}].
There is a table of expansions of special hypergeometric functions.
There are over 100 more special expansions of tabulated in Series2.m. The interested user can consult the source code (search for HYPERLIST).
