+genconfigheader.sh
+------------------
+
+Usage: `genconfigheader.sh <output_header_file> [CFLAGS]`
+
+Generate a build configuration header from CFLAGS arguments
+
+ - Arguments on the form `-Dmacro_name=macro_value` will be converted to
+   the form `#define macro_name macro_value`
+ - Arguments given on the form `-Dmacro_name` will be converted to the form `#define macro_name 1`
+ - The output file will be overwritten if it already exists _and_ the new output file's contents differs from the old file.
+
+By not replacing the output file on every run, make can still use the file
+modification times for dependency calculations.
