Fdr is a file descriptor redirector; a utility
that executes a specified command with various
file descriptor redirections in place. The bash
shell provides very flexible redirection
facilities for command pipelines. In certain
cases, however, this redirection is inapplicable
without invoking a subshell (for example,
separating the two stderr's from 'time cmd'). Fdr
is a lightweight alternative to using a full bash
interpreter for these cases.
