    perf trace beauty prctl: Default header_dir to cwd to work without parms · 0d690fc0
    Arnaldo Carvalho de Melo 提交于
    Useful when checking the effects of header synchs for the files it uses
    as a input to generate string tables, in retrospect this is how it
    should've been done from day 1, not requiring the header_dir to be set
    on the Makefile, will change everything later, so that the only parm,
    common to all generators will be $(srctree) and $(beauty_outdir).
    
    So, to see what it generates, just call it without any parameters:
