/* 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]
