+The compiler-specific packages implement functions for generating properly
+formatted commandlines for the compiler being used. Each package
+defines two primary functions 'format_linker_cmd()' &
+'format_compiler_cmd()' that accepts a list of named arguments (a
+hash) and returns a list of formatted options suitable for invoking the
+compiler. By default, if the compiler supports scripting of its
+operation then a script file is built containing the options while
+those options are removed from the commandline, and a reference to the
+script is pushed onto the commandline in their place. Scripting the
+compiler in this way helps to avoid the problems associated with long
+commandlines under some shells.

-formatted commandlines for the compiler being used. Each package
-defines two primary functions 'format_linker_cmd()' &
-'format_compiler_cmd()' that accepts a list of named arguments (a
-hash) and returns a list of formatted options suitable for invoking the
-compiler. By default, if the compiler supports scripting of its
-operation then a script file is built containing the options while
-those options are removed from the commandline, and a reference to the
-script is pushed onto the commandline in their place. Scripting the
-compiler in this way helps to avoid the problems associated with long
-commandlines under some shells.
