NAME

       mkc_check_custom - run user's custom checks.

SYNOPSIS

       mkc_check_custom [-r] sourcefile
       mkc_check_custom cmd [args...]
       mkc_check_custom -h

DESCRIPTION

       If  cmd  is  executable  mkc_check_custom  runs  cmd  args.  Otherwise it tries to compile
       sourcefile and output 1 if compilation succeeded  and  0  otherwise.   If  -r  option  was
       applied  it  runs  a compiled program.  What type of compiler to use depends on sourcefile
       extension. '.c' corresponds  to  ${CC}  (C  language),  '.cc',  '.cxx',  '.C'  and  '.cpp'
       correspond to ${CXX} (C++ language).

       -m text
              Message mkc_check_custom outputs.
              The default is "custom test sourcefile_or_cmd".

       -s     mkc_check_custom outputs an exit status of cmd args.

       -d     Delete cache files.
