-Then you can build that configuration using `make CONF_NAME=<name>` or `make
-CONF=<pattern>`, where `<pattern>` is a substring matching one or several
-configurations, e.g. `CONF=debug`. The special empty pattern (`CONF=`) will
-match *all* available configuration, so `make CONF= hotspot` will build the
-`hotspot` target for all configurations. Alternatively, you can execute `make`
-in the configuration directory, e.g. `cd build/<name> && make`.
+Then you can build that configuration using `make CONF=<selector>`, where
+`<selector>` is interpreted as follows:
+
+* If `<selector>` exacly matches the name of a configuration, this and only
+  this configuration will be selected.
+* If `<selector>` matches (i.e. is a substring of) the names of several
+  configurations, then all these configurations will be selected.
+* If `<selector>` is empty (i.e. `CONF=`), then all configurations will be
+  selected.
+* If `<selector>` begins with `!`, then all configurations **not** matching the
+  string following `!` will be selected.
+
+A more specialized version, `CONF_NAME=<name>` also exists, which will only
+match if the given `<name>` exactly matches a single configuration.

+Alternatively, you can execute `make` in the configuration directory, e.g. `cd

+# This file contains functionality related to handling paths for source files
+# and object files. This is complicated by the fact that we usually, but not
+# always, use absolute instead of relative paths. It is further complicated
+# by the fact that not all tools allow inputting large lists of files as
+# "@-files", which we normally use to avoid hitting command line length limits.
+# Finally this file contains functionality for locating all source code files
+# that should be included in the compilation.
+
+################################################################################
+# When absolute paths are not allowed in the output, and the compiler does not
+# support any options to avoid it, we need to rewrite compile commands to use
+# relative paths. By doing this, the __FILE__ macro will resolve to relative
+# paths. The relevant input paths on the command line are the -I flags and the
+# path to the source file itself.
+#
+# The macro MakeCommandRelative is used to rewrite the command line like this:
+# 'CD $(WORKSPACE_ROOT) && <cmd>'
+# and changes all paths in cmd to be relative to the workspace root. This only
+# works properly if the build dir is inside the workspace root. If it's not,
+# relative paths are still calculated, but depending on the distance between the
+# dirs, paths in the build dir may end up as essentially absolute anyway.

+# dependency files to contain paths compatible with make.

 source/target is set to 1.7 in the makefile and build.xml, because of
 support in jdk 14 compiler. To check compatibility with jdk1.4 you can
 use "-source 1.4 -target 1.4" options and jdk1.7.
+Yo can use TARGET/SOURCE of makefile and -Dtarget/surce to set them up for your convinience.
