// Implementation version 1 of algorithm class to construct PHOS track segments
-// Associates EMC and PPSD clusters
-// Unfolds the EMC cluster
-//
-//*-- Author: Dmitri Peressounko (RRC Ki & SUBATECH)
+// Track segment for PHOS is list of
+// EMC RecPoint + (possibly) CPV RecPoint
+// To find TrackSegments we do the following:
+// for each EMC RecPoints we look at
+// CPV RecPoints in the radious fRcpv.
+// If there is such a CPV RecPoint,
+// we make "Link" it is just indexes of EMC and CPV RecPoint and distance
+// between them in the PHOS plane.
+// Then we sort "Links" and starting from the
+// least "Link" pointing to the unassined EMC and CPV RecPoints assing them to
+// new TrackSegment.
+// If there is no CPV RecPoint we make TrackSegment
+// consisting from EMC alone. There is no TrackSegments without EMC RecPoint.
+//// In principle this class should be called from AliPHOSReconstructor, but
+// one can use it as well in standalone mode.
+// Use case:
+// root [0] AliPHOSTrackSegmentMakerv1 * t = new AliPHOSTrackSegmentMaker("galice.root", "tracksegmentsname", "recpointsname")
+// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
+// // reads gAlice from header file "galice.root", uses recpoints stored in the branch names "recpointsname" (default = "Default")
+// // and saves recpoints in branch named "tracksegmentsname" (default = "recpointsname")
+// root [1] t->ExecuteTask()
+// root [3] t->SetTrackSegmentsBranch("max distance 5 cm")
+// root [4] t->ExecuteTask("deb all time")
+//
