MKC_CHECK_CUSTOM(1)					     MKC_CHECK_CUSTOM(1)

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  lan-
     guage), '.cc', '.cxx', '.C' and '.cpp' correspond to ${CXX} (C++ language).
