I'm executing some msdeploy commands from powershell and when using command with spaces inside i have to use 4!! double qoutoes. Msdeploy command need single double quotes and i'm guessing that other double quotes are discarded in parsing process. Where can i get detailed description(algoritm, whitepaper) of what is happening at this 4 backtick stuff  - page 311 in first edition of Powershell in action:

dir thumb````[*

Explanation from the book: Single backtick fails because it is discarded in parsing process. It takes four backticks to cause square bracket to be treated as a regular character. I guess it's the same issue as with my 4 double quotes.

Example:

& "$msdeployDir\msdeploy.exe" -verb:sync "-source:contentpath=$workingDir\Run_script.ps1" "-dest:contentpath=$destTempDir\database\Run_script.ps1$destination" -postsync:runcommand=""""start powershell $destTempDir\database\run_script.ps1 $destTempDir\database $dbConnection""""

I'm running this on powershell v2 (included in windows 7)
