hello-exe: unknown RTS option: -N
hello-exe:
hello-exe: Usage: <prog> <args> [+RTS <rtsopts> | -RTS <args>] ... --RTS <args>
hello-exe:
hello-exe:    +RTS    Indicates run time system options follow
hello-exe:    -RTS    Indicates program arguments follow
hello-exe:   --RTS    Indicates that ALL subsequent arguments will be given to the
hello-exe:            program (including any of these RTS flags)
hello-exe:
hello-exe: The following run time system options are available:
hello-exe:
hello-exe:   -?       Prints this message and exits; the program is not executed
hello-exe:   --info   Print information about the RTS used by this program
hello-exe:
hello-exe:   -K<size>  Sets the maximum stack size (default: 80% of the heap)
hello-exe:             Egs: -K32k -K512k -K8M
hello-exe:   -ki<size> Sets the initial thread stack size (default 1k)  Egs: -ki4k -ki2m
hello-exe:   -kc<size> Sets the stack chunk size (default 32k)
hello-exe:   -kb<size> Sets the stack chunk buffer size (default 1k)
hello-exe:
hello-exe:   -A<size> Sets the minimum allocation area size (default 512k) Egs: -A1m -A10k
hello-exe:   -n<size> Allocation area chunk size (0 = disabled, default: 0)
hello-exe:   -O<size> Sets the minimum size of the old generation (default 1M)
hello-exe:   -M<size> Sets the maximum heap size (default unlimited)  Egs: -M256k -M1G
hello-exe:   -H<size> Sets the minimum heap size (default 0M)   Egs: -H24m  -H1G
hello-exe:   -m<n>    Minimum % of heap which must be available (default 3%)
hello-exe:   -G<n>    Number of generations (default: 2)
hello-exe:   -c<n>    Use in-place compaction instead of copying in the oldest generation
hello-exe:            when live data is at least <n>% of the maximum heap size set with
hello-exe:            -M (default: 30%)
hello-exe:   -c       Use in-place compaction for all oldest generation collections
hello-exe:            (the default is to use copying)
hello-exe:   -w       Use mark-region for the oldest generation (experimental)
hello-exe:   -I<sec>  Perform full GC after <sec> idle time (default: 0.3, 0 == off)
hello-exe:
hello-exe:   -T         Collect GC statistics (useful for in-program statistics access)
hello-exe:   -t[<file>] One-line GC statistics (if <file> omitted, uses stderr)
hello-exe:   -s[<file>] Summary  GC statistics (if <file> omitted, uses stderr)
hello-exe:   -S[<file>] Detailed GC statistics (if <file> omitted, uses stderr)
hello-exe:
hello-exe:
hello-exe:   -Z       Don't squeeze out update frames on stack overflow
hello-exe:   -B       Sound the bell at the start of each garbage collection
hello-exe:
hello-exe:   -h       Heap residency profile (output file <program>.hp)
hello-exe:   -i<sec>  Time between heap profile samples (seconds, default: 0.1)
hello-exe:
hello-exe:   -C<secs>  Context-switch interval in seconds.
hello-exe:             0 or no argument means switch as often as possible.
hello-exe:             Default: 0.02 sec.
hello-exe:   -V<secs>  Master tick interval in seconds (0 == disable timer).
hello-exe:             This sets the resolution for -C and the heap profile timer -i,
hello-exe:             and is the frequence of time profile samples.
hello-exe:             Default: 0.01 sec.
hello-exe:
hello-exe:   --install-signal-handlers=<yes|no>
hello-exe:             Install signal handlers (default: yes)
hello-exe:   -e<n>     Maximum number of outstanding local sparks (default: 4096)
hello-exe:   -xq       The allocation limit given to a thread after it receives
hello-exe:             an AllocationLimitExceeded exception. (default: 100k)

hello-exe: RTS options may also be specified using the GHCRTS environment variable.

hello-exe: Other RTS options may be available for programs compiled a different way.
