+/* Coreutils 6.12 man page says:
+ *        mktemp [OPTION]... [TEMPLATE]
+ * Create a temporary file or directory, safely, and print its name. If
+ * TEMPLATE is not specified, use tmp.XXXXXXXXXX.
+ * -d, --directory
+ *        create a directory, not a file
+ * -q, --quiet
+ *        suppress diagnostics about file/dir-creation failure
+ * -u, --dry-run
+ *        do not create anything; merely print a name (unsafe)
+ * --tmpdir[=DIR]
+ *        interpret TEMPLATE relative to DIR. If DIR is not specified,
+ *        use  $TMPDIR if set, else /tmp.  With this option, TEMPLATE must
+ *        not be an absolute name. Unlike with -t, TEMPLATE may contain
+ *        slashes, but even here, mktemp still creates only the final com-
+ *        ponent.
+ * -p DIR use DIR as a prefix; implies -t [deprecated]
+ * -t     interpret TEMPLATE as a single file name component, relative  to
+ *        a  directory:  $TMPDIR, if set; else the directory specified via
+ *        -p; else /tmp [deprecated]
