Enable latex-export-logging in org-mode

There are words that may take minute(s)

Emacs version: GNU Emacs 26.1(Also works in Emacs 24 or maybe even in earlier versions)

By default, when exporting latex and PDF file from emacs org-mode, log files are removed when the process finishes, you may want to reserve it.

To make emacs stop removing log files, do as below:

M-x -> customize-variable, RET -> org-latex-remove-logfiles

By default this variable is set to true, means log files are removed automatically, then you just need to toggle it to false, save, restart Emacs, and you're good to go 😀
