I want to count specific words in a document. For example how many times
appears thos words in a documente:

-Develope
-Implement
-Ensure
etc.

I want to obtain a table at the end of the document or in other documents
that looks like:

-Develope: 11 times
-Implement: 8 times
-Ensu 2 times
etc.

Generally in certains technical books you can find at the end in what pages
appears some terms. It's like this, but only to count.

Thank you

Fabian
