-# EBCDIC codepages for S/390, with LF and NL codes swapped
-# Starting with ICU 2.4, the swapping is done by modifying the
-# normal tables at runtime instead of at build time.
-# Append UCNV_SWAP_LFNL_OPTION_STRING to the "ibm-CCSID" name to select this.
-#
-# Example: "ibm-1047,swaplfnl" or "ibm-1047" UCNV_SWAP_LFNL_OPTION_STRING
-#
-# This avoids the duplication of all EBCDIC SBCS and mixed-SBCS/DBCS
-# mapping files.
-
-# Some examples below for declaring old-style, obsolete aliases with the "-s390"
-# suffix to map to the new-style, recommended names with the option added.
-# These are listed here for backward compatibility.
-# Do not use these; instead use the normal converter name with the option
-# added as recommended above.
-
-# Note: It is not possible to define an alias (non-initial name in a line here)
-# that itself contains a converter option like this one for swapping LF<->NL.
-# Such names would never be found because ucnv_open() will first parse and strip
-# options before looking up a name in this table.
-# ucnv_open() then parses the lookup result (the canonical name on the left
-# in lines here) as well.
-
-# This also means that it is not necessary to add anything to convrtrs.txt
-# for converter names like "ibm-1026,swaplfnl" to work -
-# they are already covered by the normal option parsing together with the
-# regular, option-less alias elsewhere in this file.
