-
-
-## ------------------------------- ##
-## Preprocessor features           ##
-## ------------------------------- ##
-#
-# Supported features are:
-#
-# include   : correctly process #include directives and -I
-# define    : correctly process -D
-# substitute: substitute macros in Fortran code
-#             (some preprocessors touch only lines starting with #)
-# wrap      : wrap lines that become too long through macro substitution
-#             fpp is probably the only preprocessor that does this.
-# cstyle    : Do not suppress C style comments (-C option in cpp)
-# CSTYLE    : *Do* suppress C style comments
-#             (e.g. code contains C-style comments, and compiler may not
-#             know how to handle them)
-# cxxstyle  : Do not suppress C++ style comments (default)
-# CXXSTYLE  : *Do* suppress C++ style comments (seems unlikely, but in here
-#             for completeness)
-#
-# Features can be abbreviated: i, in, inc etc. are equivalent to include.
-# Features can be deselected (feature not needed) by prepending "no",
-#   e.g. nodef (=nodefine), now (=nowrap).
-#
-# Default for the feature list is
-#       [include define substitute nowrap nocstyle noCSTYLE cxxstyle]
-# Feature requirements corresponding to the defaults may be omitted
-#
-# Note that "wrap" implies "substitute", and CSTYLE and cstyle cannot
-# be requested at the same time. The macro adjusts this automatically.
