% \section{Introduction}
% When dealing with graphics, there are different scaling demands. For \emph{absolute} scaling, a width and/or height is given. Opposed to that, for relativ scaling, a horizontal and/or vertical scaling factor is needed. This package only is about absolute scaling of tikzpicture environments. The different absolute scaling demands and their solutions are shown in table \ref{scalingDemands}.

% \section{Compatibility}
% Using both the externalization library and tikzscale seems to have a race condition when a makefile is used with multiple jobs (-j$X$ with $X > 1$). The probability of getting errors increases with the number of jobs. For $X = 1$, obviously, no race condition could be observed. You should either avoid using mode \emph{list and make} or have only one job if you want to be on the safe side.

% \item It might be a good idea to use the file names as figure names, but probably only if the name was not already set by the user. Additionally, there must be taken care to not try to write into a directory where there is no write access (e.g. reading a graphic from a system wide TeX installation)
% \item if graphic files are located in a subdirectory, the externalized files should also be in that subdirectory.
% \item allow in-file graphics by redefining the tikzpicture environment and accepting tikzscale and tikz options. The tikzscale options are evaluated using key filtering (tikz library) and the tikz options are forwarded.
