Enable Versioning SharePoint 2010 Document Library reading CSV file using Powershell

My requirement is update all document libraries version history “No Version” to “Major version”. when i loop through all document libraries from all sites it is updating so many out of box document libraries. I dont want to touch any out of box or other libraries.  so i come up with one csv file which is having my document library names and site relative url as shown below.

here DocLibName, URL are headings. for home site you dont need to specify any value for URl like below.

copy to notepad file and Save as DocLibraries.csv file. dont change below heading names.

DocLibName	URL
Shared Documents
Resource Library	subsite1
Meeting Minutes	sbusite2
Archives	subsite3
Final Documents	susbsite3

$URL = "http://spsev5:8003/"

$site = New-Object Microsoft.SharePoint.SPSite($URL)

#$web = $site.openweb("")

$InputFile = "D:\Development\Surya\DocLibraries.csv"

$file = ipcsv $InputFile
