+ +string Add string as a new argument (at the end of the command line).
+ Multi-word command lines can be added with +x +y
+ s/x/y/ substitute x for y in the command line. X must be an entire
+ argument, and can be a regular expression as accepted by the
+ POSIX regexp code. Y will be substituted as a single argument,
+ and will not have regexp replacements added in.
+ xoption Removes argument matching option
+ Xoption Removes argument matching option and following word
+ Ox Removes any optimization flags in command line and replaces
+ with -Ox.
+
+
+ Here's some examples:
+ O2
+ s/precomp-trustfile=foo//
+ +-fexplore-antartica
+ +-fast
+ s/-fsetvalue=* //
+ x-fwritable-strings
+ s/-O[0-2]/-Osize/
+ x-v
+ X-o +-o +foo.o
+
+ Option substitutions are processed from left to right; matches and changes
+ are cumulative. An error in processing one element (such as trying to
+ remove an element and successor when the match is at the end) cause the
+ particular change to stop, but additional changes in the environment
+ variable to be applied.
+
+ Key details:
+ * we always want to be able to adjust optimization levels for testing
+ * adding options is a common task
+ * substitution and deletion are less common.
+
+ If the first character of the environment variable is #, changes are
+ silent. If not, diagnostics are written to stderr explaining what
+ changes are being performed.
