HistoryPx uses proxy commands to add extended history information to

PowerShell. This includes the duration of a command, a flag indicating whether

a command was successful or not, the output generated by a command (limited to

a configurable maximum value), the error generated by a command, and the

actual number of objects returned as output and as error records.  HistoryPx

also adds a "__" variable to PowerShell that contains the output from the last

command, even if the last command did not generate any output.  Lastly,

HistoryPx includes commands to manage the memory footprint that is used by

extended history information.

.DESCRIPTION

    The Set-ExtendedHistoryConfiguration command sets the extended history configuration for the session.
