branch: master
commit 8c7081cdde4fdfe3b1cb690f0fe3ff1d5ab5becf
Author: Mohammad Akhlaghi <mohammad@akhlaghi.org>

    Book: LaTeX externalization command with no line breaks
    
    Until now, the LaTeX (TiKZ package) externalization command (a simple shell
    command) was broken into multiple lines in 'doc/plotsrc/all.tex'. On some
    systems, this would result in the non-creation of the final EPS files for
    each figure that we draw in TiKZ (the broken lines were not interpreted in
    the "externalization" command).
    
    With this commit, the full externalization command has been brought into
    one line. Also, instead of ';' between the commands, we are now using '&&'
    so it doesn' continue if one command fails.
    
    This issue was reported by Bharat Bhandari.
