 PATH Names
 ======================================================================
 
-Pathnames to executables in eshell.exe have to be written with
-backslashes '\', file arguments to perl with slashes '/'. The default
-drive of perl is the same as the drive perl.exe is located on, the
-default path seems to be '/'.
+ESHELL looks for executables in ?:/System/Programs. The SIS file
+installs perl in this special folder directory. The default drive and
+path are the same as folder the executable resides. The EPOC
+filesystem is case-preserving, not case-sensitive.
+
+EPOC uses the ?: syntax for establishing a search order: First in C: (RAM),
+then on D: (CF Card) and last in Z: (ROM).
+
+The perl @INC search path is now implemented with '?:'. Your perl
+executable can now live on a different drive than the perl library or
+even your scripts.
 
-i.e. command lines look a little bit funny:
+ESHELL paths have to be written with backslashes '\', file arguments
+to perl with slashes '/'. Remember that I/O redirection is done
+internally in perl, so please use slashes for redirects.
