I would be willing to help with what I can. I am not by any means an advanced
or for that matter probably even considered intermediate programmer. I pretty
much hack my way through things to get them to work how I want them. Simple
things for regular perl coders may take them 10 mins, takes me like 3-4 hours.
As an example. I wanted a slightly different result that is considered part of
the RANCID-CONTENT-TYPE, so I wrote it today and a script to convert the files
over. What I here took about 4 hours to get it to work and make sure it worked
on all my Cisco equipment. :(
Have not done any coding with Expect.pm but I did hear it was limited. I am not
sure how much truth there is to that.
But if the project is willing to move in that direction I will provide what ever
coding I can provide.
