-Usage: $Pgm [mkdependHS options] [-- GHC options --] srcfile1 [srcfile2 ...]
-
-Options recognised wherever they occur (mkdependHS or GHC):
-
- -D<blah> A cpp #define; usual meaning
- -i<dirs> Add <dirs> (colon-separated) to list of directories
- to search for "import"ed modules
- -I<dir> Add <dir> to list of directories to search for
- .h files (i.e., usual meaning)
- -package <blah> This program uses this GHC system library; take
- appropriate action (e.g., recognise when they are
- "import"ing a module from that library).
- -osuf <osuf> Use <osuf> as the "object file" suffix ( default: o)
-
-mkdependHS-specific options (not between --'s):
-
- -v Be verbose.
- -v -v Be very verbose.
- -w No warnings
- -f blah Use "blah" as the makefile, rather than "makefile"
- or "Makefile".
- -cpp Wash the input files through cpp(1).
- -s <suf> Make extra dependencies for files with
- suffix <suf><osuf>; thus, "-o hc -s _a" will
- make dependencies both for .hc files and for .a_hc
- files. (Useful in conjunction with NoFib "ways".)
- --exclude-module=<file>
- Regard <file> as "stable"; i.e., eXclude it from having
- dependencies on it.
- -x same as --exclude-module
- --exclude-directory=<dirs>
- Regard : separated list of directories as containing stable,
- don't generate any dependencies on modules therein.
- -Xdirs same as --exclude-directory
- --include-prelude
- Regard prelude libraries as unstable, i.e., generate dependencies
- on prelude modules. This option is normally only used by the
- various system libraries. If a -package option is used, dependencies
- will also be generated on the library's interfaces.
- --include-module=<file>
- Regard <file> as not "stable"; i.e., generate dependencies
- on it (if any). This option is normally used in conjunction
- with the --exclude-directory option.
