Check and Create MD5 Checksum Files

Description:

     'checkMD5sums' checks the files against a file 'MD5'.

Usage:

     checkMD5sums(package, dir)

Arguments:

 package: the name of an installed package

     dir: the path to the top-level directory of an installed package.

Details:

     The file 'MD5' which is created is in a format which can be
     checked by 'md5sum -c MD5' if a suitable command-line version of
     'md5sum' is available.  (One is supplied in the bundle at <URL:
     http://www.murdoch-sutherland.com/Rtools/tools.zip>.)

     If 'dir' is missing, an installed package of name 'package' is
     searched for.

     The private function 'tools:::.installMD5sums' is used to create
     'MD5' files in the Windows build.

Value:

     'checkMD5sums' returns a logical, 'NA' if there is no 'MD5' file
     to be checked.
