//  Function:   BuildScriptAndGetActInfo
//
//  Synopsis:   Builds the script file and fills in the ACTINFO structure
//              member in the PACKAGEDETAIL structure.
//
//  Arguments:  [szScriptRoot] - [in] the subdirectory that the script file
//                                should be place in.
//              [pd]           - [in/out] package detail structure - see
//                                notes for complete list of fields that
//                                should be filled in and the list of fields
//                                that are set on return
//
//  Returns:    S_OK - success
//              <other> - error
//
//  Modifies:   all fields under pd.pActInfo (only on success)
//              also modifies pd.pInstallInfo->cScriptLen
//
//  History:    1-14-1998   stevebl   Created
//
//  Notes:      On input:
//              pd.cSources must be >= 1.
//              pd.pszSourceList[] contains the MSI package and the list of
//              (if any) transforms to be applied.
//              pd.pPlatformInfo should be completely filled in (only one
//              locale).
//              pd.pInstallInfo->pszScriptFile contains the name of the
//              script file to be generated.
//
//              On output:
//              The script file will be generated under the appropriate name
//              and in the appropriate directory.
//              pd.pActInfo will be completely filled in.
