#
# Syntax:  rmtex [-h] [-f] [filename [...]]
#
# Purpose: Removes all auxiliary files created by latex for the given files.
#          So the files .log, and all files that have the same prefix as
#          filename  and the extension .bak, .aux, .bbl, .blg, .dvi, .lof,
#          .log, .lot, .toc, .ilg, .ind, .idx, .inx, .ent, .out, .los, .thm,
#          .shm, .vrb, .nav, .spl, .cb, or .pfg .
#          If filename is empty then all files with the extensions mentioned
#          above will be removed.
#          For security for files for which the corresponding latex file is
#          no longer present then the program will ask for confirmation of
#          the removal (except if the extension is .bak).
#          Use the -f flag to remove those files without asking for
#          confirmation.
#          The -h flag shows the help info for this command.
