------------------
Installation
------------------

SendEmail is a perl script/program, and only needs to be copied to a directory
in your path to make it accessible.  Most likely the following steps will
be sufficient:

1) Extract the package
    tar -zxvf sendEmail-v1.XX.tar.gz

2) Copy the sendEmail script to /usr/local/bin
    cp -a sendEmail-v1.XX/sendEmail /usr/local/bin

3) Make sure its executable
    chmod +x /usr/local/bin/sendEmail

4) Run it
    sendEmail
      or
    /usr/local/bin/sendEmail

NOTES:
  * Running sendEmail without any arguments will produce a usage summary.
  * SendEmail is written in Perl, so no compilation is needed.
  * On a Unix/Linux OS if your perl binary is not installed at /usr/bin/perl
    you may need to edit the first line of the script accordingly.
