\ProvidesFile{sphinxlatexadmonitions.sty}[2021/01/27 admonitions]
% Provides support for this output mark-up from Sphinx latex writer:
%
% - sphinxadmonition (environment)
% This is a dispatch supporting
%
% - note, hint, important, tip (via sphinxlightbox)
% - warning, caution, attention, danger, error (via sphinxheavybox)
%
% Each sphinx<notice name> environment can be redefined by user.
% The defaults are customizable via various colour and dimension
% settings, cf sphinx docs (latex customization).
%
% Requires:
\RequirePackage{framed}% used by sphinxheavybox
%
% Dependencies (they do not need to be defined at time of loading):
% - of course the various colour and dimension options handled via sphinx.sty
% - \sphinxstrong (for sphinxlightbox and sphinxheavybox)
% - dimension register \spx@image@maxheight from sphinxlatexgraphics.sty
% - \savenotes/\spewnotes from sphinxpackagefootnote (for sphinxheavybox)
% Provides: (also in sphinxlatexliterals.sty)
