+.SYNOPSIS
+Summarizes upload.getFile requests in telesrv logs.
+
+.DESCRIPTION
+Use this after opening media history in TDesktop or Android. It groups
+upload.getFile RPCs by client_type/app_version and reports request count and
+duration percentiles. Pass -SinceLine from a previous baseline if desired.
