# Syntax:  tpurge [-h] [dir]
#
# Purpose: Removes all auxiliary files created by latex from a directory.
#          More specifically, removes files with extensions .bak, .aux, .bbl,
#          .blg, .dvi, .lof, .log, .lot, .ind, .ilg, .inx, .toc, .idx, .ent,
#          .out, .los, .thm, and .pfg from the directory  dir  and its
#          subdirectories. Also removes the hidden .log files.
#          The default value for  dir  is the current directory.
#          The -h flag shows the help info for this command.
