+ * Decide on appropriate memory setting for Jalview based on the two arguments
+ * values: jvmmempc - the maximum percentage of total physical memory to
+ * allocate, and jvmmemmax - the maximum absolute amount of physical memory to
+ * allocate. These can be provided as arguments. If not provided as arguments
+ * (or set as null) system properties will be used instead (if set). The
+ * memory setting returned will be the lower of the two values. If either of
+ * the values are not provided then defaults will be used (jvmmempc=90,
+ * jvmmemmax=32GB). If total physical memory can't be ascertained when
+ * jvmmempc was set or neither jvmmempc nor jvmmemmax were set, then jvmmemmax
+ * defaults to a much safer 8GB. In this case explicitly setting jvmmemmax and
+ * not setting jvmmempc can set a higher memory for Jalview. The calculation
+ * also tries to ensure 0.5GB memory for the OS, but also tries to ensure at
+ * least 0.5GB memory for Jalview (which takes priority over the OS) If there
+ * is less then 0.5GB of physical memory then the total physical memory is
+ * used for Jalview.
+ *
+ * @param jvmmemmaxarg
+ * Maximum value of memory to set. This can be a numeric string
+ * optionally followed by "b", "k", "m", "g", "t" (case insensitive)
+ * to indicate bytes, kilobytes, megabytes, gigabytes, terabytes
+ * respectively. If null a default value of 32G will be used. If null
+ * and either physical memory can't be determined then the default is
+ * 8GB.
+ * @param jvmmempcarg
+ * Max percentage of physical memory to use. Defaults to "90".
+ *
+ * @return The amount of memory (in bytes) to allocate to Jalview
