+" Vim syntax file
+" Language: Java Properties resource file (*.properties[_*])
+" Maintainer: Simon Baldwin <simonb@sco.com>
+" Last change: 26th Mar 2000
+
+" =============================================================================
+
+" Optional and tuning variables:
+
+" jproperties_lines
+" -----------------
+" Set a value for the sync block that we use to find long continuation lines
+" in properties; the value is already large - if you have larger continuation
+" sets you may need to increase it further - if not, and you find editing is
+" slow, reduce the value of jproperties_lines.
+if !exists("jproperties_lines")
+ let jproperties_lines = 256
+endif
+
+" jproperties_strict_syntax
+" -------------------------
+" Most properties files assign values with "id=value" or "id:value". But,
+" strictly, the Java properties parser also allows "id value", "id", and
+" even more bizarrely "=value", ":value", " value", and so on. These latter
+" ones, however, are rarely used, if ever, and handling them in the high-
+" lighting can obscure errors in the more normal forms. So, in practice
+" we take special efforts to pick out only "id=value" and "id:value" forms
+" by default. If you want strict compliance, set jproperties_strict_syntax
+" to non-zero (and good luck).
+if !exists("jproperties_strict_syntax")
+ let jproperties_strict_syntax = 0
+endif
+
+" jproperties_show_messages
+" -------------------------
+" If this properties file contains messages for use with MessageFormat,
+" setting a non-zero value will highlight them. Messages are of the form
+" "{...}". Highlighting doesn't go to the pains of picking apart what is
+" in the format itself - just the basics for now.
