@1010011010 If you are interested, here is the cell of the Rubi source that defines the rule for this integral 
Import["http://halirutan.github.io/Mathematica-SE-Tools/decode.m"]["http://i.stack.imgur.com/8hv1k.png"]
The comment of Albert, however, says nothing more than "Derivation: Integration by parts and ???" for this rule.
You find this rule in 3.3 u (a+b log(c (d+e x)^n))^p on Rubi's website.

@halirutan Honestly that is a fantastic package. So useful. I wonder if it's possible to get a paclet to run in the cloud...that'd make it really powerful as you could install/run Rubi for free.
The cloud still blows but it doesn't blow nearly as hard as it used to
I've actually been having people I know use it of late when they need symbolic derivatives and things

@b3m2a1 It runs with Expreduce so it's quite easy to create a server lets people use RUBI that way.

@C.E. oh that's pretty convenient. On the other hand all the post-integration simplifications won't be there.
(Well maybe Expreduce has more than I expect, but my guess is not a ton)

@b3m2a1 Then it's up to us to implement that :)

I mean, it being an open-source project. Personally, I have no expertise in such things.

@C.E. yeah me neither. I think if a new Albert Rich ever decided to do the equivalent of Rubi for simplification rules we'd be in business.
@J.M.iscomputer-less nice to see you hanging around!

@b3m2a1 yeah, I was able to take a peek because I borrowed a friend's phone. Unfortunately, I can't stay around much longer.

@b3m2a1 It might be interesting to look through sympy's source code since it is open source... if it boils down to a table of replacement rules it might be possible to implement it in Wolfram Language/Expreduce without too much trouble.

@C.E. You should post a bite-sized description (+ link) that we can pin on the right.
Please ping me when done so I can pin it.
