Hi Vasil,
Neat package. Thank you for sharing it. I get following message when Needs["TBpack`"] runs the first time and when MaTeX[] is used.
The path to Ghostscript is not configured.
Please configure Ghostscript using ConfigureMaTeX["Ghostscript" -> "path to gs executable\[Ellipsis]"]
Click here for documentation on configuring MaTeX.
When I click the link, I get a beep and the message
"paclet:MaTeX/tutorial/ConfiguringMaTeX" could not be found.
How do I configure Ghostscript?
