+\ProvidesPackage{principia}[2021/04/19 principia package version 1.3] %This is the principia package is for representing notations in Whitehead and Russell's ``Principia Mathematica" close to their appearance in the original.
%Version 1.0 (superseded by Version 1.1): Covers typesetting of notation through Volume I. 2020/10/24
-%Version 1.1 (updates): fixed the spacing of scope dots around parentheses; fixed spacing of theorem sign; fixed spacing around primitive proposition and definition signs. 2020/10/25

+%Version 1.2 (superseded by Version 1.3) (minor updates): boldfaced (`thickened') the truth-functional connectives, existential quantifier, set and relation symbols; added numerous commands for typesetting brackets and substitutions into theorems. 2021/02/25
+%Version 1.3 (minor update): removes package dependency on marvosym; updates Section A notation; removes other notations (corrected extension pending). 2021/04/19

%Principia package requirements
\RequirePackage{amssymb} %This loads the relation domain and converse domain limitation symbols.
\RequirePackage{amsmath} %This loads the circumflex, substitution into theorems, \text{}, \mathbf{}, \boldsymbol{}, \overleftarrow{}, \overrightarrow{}, etc.
\RequirePackage{graphicx} %This loads commands that flip iota for definite descriptions, Lambda for the universal class, and so on. The (superseded) graphics package should also work here, but is not recommended.
-\RequirePackage{marvosym} %This loads the male and female symbol.
\RequirePackage{pifont} %This loads the symbols such as the eight-pointed asterisk.
+%The \Female and \Male symbols are imported directly from Marvosym.
