2129 # Deletion of files made during compilation.
2130 # There are four levels of this:
2131 #   `mostlyclean', `clean', `distclean' and `maintainer-clean'.
2132 # `mostlyclean' is useful while working on a particular type of machine.
2133 # It deletes most, but not all, of the files made by compilation.
2134 # It does not delete libgcc.a or its parts, so it won't have to be recompiled.
2135 # `clean' deletes everything made by running `make all'.
2136 # `distclean' also deletes the files made by config.
2137 # `maintainer-clean' also deletes everything that could be regenerated
2138 # automatically, except for `configure'.

2140 # (less duplicated code).
