Unsure of sed notation (nu\\t.\*)

This piece of code is in a shell script I'm trying to modify to run on my system.

Code:
sed s:nu\\t.\*:"nu=0"

It's clearly a substitute script which replaces nu\\t.\* with nu = 0.

What exactly does
Code:
nu\\t.\*

demarcate though-- I thought it was just the previous nu = xxxxx (which existed and is getting overwritten) but the double forward slashes and then the t confuse me.

Thanks in advance.

NAME
impressive-gettransitions - Generate Impressive info scripts for LaTeX presentations SYNOPSIS
impressive-gettransitions FILE.tex DESCRIPTION
A simple script to produce a .info file for use with Impressive, using special comments in a LaTeX/Beamer file. FILE.tex is a file to be parsed into .info file. For each /fullpath/blah.tex /fullpath/blah.pdf.info gets produced. SYNTAX
In the LaTeX document, impressive-gettransitions counts the pages to determine the PDF slide number of each one. The simpler page changes are automatically detected, that is: egin{frame} and: pause Other, more elaborated page changes must be noted with a %O comment: item<1-> Foo item<2-> Bar %O The transition to apply can be specified in a %O comment: egin{frame} %O SlideUp OPERATION
When the .info file corresponding to the LaTeX document already exist, impressive-gettransitions does not clear it, but only adds the transitions if finds to it. Thus, if you modified your document in a way that requires to completely replace the transitions, manually clear the PageProps section of the .info file. This can be done by running the following sed command: sed -i -e "/^PageProps = {/,/^}/d" FILE.info SEE ALSO
