Reverse Words

[Joe Caverly]

ReverseWords.ps1 is a script to accept a string of words,
and display them to the console in reverse order.

I have ReverseWords.ps1 in my path,
E:\Utils\ReverseWords.ps1

R:\>which psc
psc is an alias : pshell /s %@quote[%$]

R:\>psc reversewords One Two Three
Three Two One

R:\>psc reversewords One,Two,Three
Three Two One

R:\>psc reversewords "One","Two","Three"
Three Two One

I gave DuckAI the script I had written,
and asked it to generate the comment-based help.

Thus, now I can get detailed help for ReverseWords.ps1 from the TCC command line.

R:\>psc get-help reversewords.ps1
