Powershell Cmdlet and Alias listing

Generate a list of PowerShell Cmdlets:

"Name`tSynopsis`tDescription`tFile"
ls -recurse $PSHOME *-Help.xml | foreach {
$fileName = $_.Name
$help = [xml](gc $_.fullName)
$help.helpitems.command | foreach {
write-output ([string]::format("{0}`t{1}`t{2}`t{3}",$_.details.name.trim(),$_.details.description.get_InnerText().trim(),$_.description.get_InnerText().trim().replace("`n", " "),$fileName))
}
}

Generate a list of Aliases:

"Name`tDefinition"
get-alias | sort -property Name | select Name, Definition |% {
write-output ([string]::format("{0}`t{1}", $_.Name,$_.Definition))
}

Each output is tab delimited.
