Question: How to label contours in Maple 17?

hi friends

i have a question and i could find the answer in existing questions but it was not clear at all!!!

i want to label my contours and i know that i should use lebelledcontourplot command.

But how?!
i could find an answer:

"1- First download the files located on his webpage.  Advisor6.zip    It should be zipped with 3 files in it. 

2 - Unzip them and copy them into a directory which you name, probably somewhere in the maple directory named advisor.  c:\maple12\advisor

3 - Then create a maple.ini in the maple12 directory with the following line to match your directory location  
libname:= `c:/maple12/advisor`, libname:  just like on the instruction installation page."

these are my questions:

1-how can i create a maple.ini?!
2-what should i do with the file i will create?

please explain more about the third phrase and explain exactly what should i do step by step.

thanks a lot
