+###############################
+# Wrapper for Jalview
+#
+# 2023-08-16 Jalview 2.11.3.0 has new command line arguments
+# Old command line arguments are currently detected and actioned
+# but are no longer supported and will be removed at a later date.
+#
+# See
+#   Jalview -> Help -> Documentation -> Command Line -> introduction and reference
+# or
+#   https://www.jalview.org/help/html/features/clarguments.html
+# for details of the new command line arguments.
+#
+# Note, in order to run commandline-only calls use
+#   --headless
+#
+# By default, this wrapper executes java -version to determine the JRE version
+# Set JALVIEW_JRE=j1.8 or JALVIEW_JRE=j11 to skip the version check.
+#
+# By default, this wrapper does NOT restrict the memory consumption of Jalview.
+# Set eg. JALVIEW_MAXMEM=1g to set the maximal memory of Jalview's VM
+#
+# This script is maintained in the Jalview repository in utils/conda/jalview.sh
