# Warning
# =======
# As of ICU 51.1, ICU as obtained from the ICU repository does not
# build with the Mozilla build tools for Windows. Check
# http://bugs.icu-project.org/trac/ticket/9985
# whether this has been addressed in the version you're updating to.
# If not, obtain the patch "Make ICU build with Mozilla build for Windows" from
# https://bugzilla.mozilla.org/show_bug.cgi?id=724533
# and reapply it after running update-icu.sh (additional updates may be needed).
# If the bug has been addressed, please delete this warning.

# Usage: update-icu.sh <URL of ICU SVN with release>
# E.g., for ICU 50.1.1: update-icu.sh http://source.icu-project.org/repos/icu/icu/tags/release-50-1-1/
