+# B language keywords
+# by Gyorgy Rotter
+#
+# For the proper syntax highlight the order of the keywords are
+# important. This is why the related keywords are not listed in a block.
+# To create semantic relationship between the keywords I used groups.
+# Some keywords are in a group (the name of the group is
+# indicated in a commented line above the keyword definition)
+#
+# With the one-liner for example we could replace
+# the color of the keywords which are the members of the
+# "Sequences" group from "yellow" to "red"...
+#
+#  echo Sequences yellow red | xargs -l bash -c 'sed -z "s/\(# $0\n[^\n]*\)$1/\1$2/g" b.syntax'
+#         ^         ^     ^
+#         |         |     |
+#         |         |     -- new_color
+#         |         -- actual_color
+#         -- groupname
+#
+#
+# Usable groups:
+#   Relations, Sequences, Logical, Arithmetic, Sets, Substitutions
+#
+# Usable colors:
+#   described in the Syntax file
