This file describes the Rtools/bin collection, a set of tools to help
build and test R for Windows.

basename cat cmp comm cp cut date diff du echo expr gzip ls makeinfo
mkdir mv rm rsync sed sort texindex touch uniq

These are extracted from the cygwin collection
(http://sources.redhat.com/cygwin and several mirrors). 

file is compiled from the sources, to look for the "magic" file in 
the same directory as file.exe.

sh is an older version of the Cygwin sh, from before they started
to require Unix-style line endings in scripts.

make is compiled from the sources, altered to use sh.exe in the path 
if this exists (rather than /bin/sh.exe).

tar is compiled from the sources, altered to accept Windows drives
in the path specification.

zip, unzip from the Info-ZIP collection.

Please note that find and sort have the same names as Windows
utilities; if you want to access the Windows ones while ours are on
the path, you could rename our utilities and edit the FIND and SORT
macros in src/gnuwin32/MkRules, but note that this option is rarely
tested:  we prefer the Rtools utilities to the Windows ones.


Extras
======

Also included are egrep, find, gawk, grep, head and wc (which used to be
