Hi,

It would be interesting to add this to the complete build, or to the 
inspection script.

The rule takes all the files following the pattern *.hpp in the boost 
directory.
Are there other files to check?
Do we need to check for all these files?

I don't know if all the files must follow this rule, in principle only the 
public files need to follow it. I don't see any way to kwnow that other than 
explicitly by the library owner. So maybe we need a rule that applies to 
some specific files

test-suite units_headers :
  [ check_header : boost/header1.hpp ]
  [ check_header : boost/header2.hpp ]
  ...
  [ check_header : boost/headerN.hpp ]
  ;

If a library owner want to check for all the *.hpp files in its own 
subdirectory she can write

test-suite units_headers :
  [ check_headers : ../../.. : boost/units : *.hpp ]

The check_header/s rule can be added to the testing module, as it is already 
the case of compile, run, ...

Do you think that this should be added to boost?

Best,

Vicente
