2086 # Deletion of files made during compilation.
2087 # There are four levels of this:
2088 #   `mostlyclean', `clean', `distclean' and `maintainer-clean'.
2089 # `mostlyclean' is useful while working on a particular type of machine.
2090 # It deletes most, but not all, of the files made by compilation.
2091 # It does not delete libgcc.a or its parts, so it won't have to be recompiled.
2092 # `clean' deletes everything made by running `make all'.
2093 # `distclean' also deletes the files made by config.
2094 # `maintainer-clean' also deletes everything that could be regenerated
2095 # automatically, except for `configure'.
2096 # We remove as much from the language subdirectories as we can
2097 # (less duplicated code).
