       makepplog option ...

       mppl option ...

       Makepp by default writes a detailed log of its decision finding and actions.  So as to not
       waste its time with pretty printing, this data is dumped in a compact, cryptic format.
       This tool does the pretty printing and filtering in various formats.  For a less detailed
       but prettier graphical view see makeppgraph.

       This is solely based on the contents of the log file (.makepp/log), so it can be performed
       at any time as long as you preserve the file, and even on a different machine.  Every time
       makepp stops when running with option "--loop", you get a page break.  Valid options are:

       -A filename
       --args-file=filename
       --arguments-file=filename
           Read the file and parse it as possibly quoted whitespace- and/or newline-separated
           options.

       -c
       --current-working-directory
       -C number
       --current-working-directory-and-up=number
           The first two options strip the current directory from the front of all filenames it
           outputs.  The second two additionally replace number directories up from here, with
           the necessary number of ../ entries.

           These options only work meaningfully when you call makepplog in the same directory
           makepp ran, or one near there.

       -d
       --set-directory
           Virtually switch to the directory where the log file was originally produced.  If you
           copied or moved it from there, this is necessary for "-c" (which is implied by this
           option) to shorten the original path.

       -f
       --follow
           As in "tail" command, process more lines of logfile as it grows.

       -?
       -h
       --help
           Print out a brief summary of the options.

       -i
       --install-dirs
       --installation-directories
           These options replace the invocation of makepp and the pathes to the built in
           makefiles with .../ so as to keep odd pathes out of your sight.

       -k list
       --keys=list
       --keylist=list
           The list specifies one or more space separated Shell style patterns (with [xyz], ?, *,
           {a,bc,def}).  Remember to protect these from your Shell by quoting.  These are matched
           against the message keys (as shown by "--showkey").  Each pattern may be preceded with
           an exclamation mark ("!") or a caret ("^") to exclude the matched keys from those
           selected before instead of adding them to the selection.  If the first pattern starts
           with an exclamation mark, it operates on all keys.  There are a few key prefixes with
           fixed meanings so you can select categories of keys:

           BC* All build cache related messages.

           BUILD*
               All build reason related messages.

           LOAD*
               All makefile loading related messages.

           REP*
               All repository related messages.

           RULE*
               All rule related messages.

           SCAN*
               All scanning related messages.

               --keys='LOAD* RULE*'        # Only makefile loading and rule messages.
               --keys='!BUILD* *CMD'       # No build messages, except BUILD_CMD.

       -K
       --showkey
           This prefixes each output line with the internal name of the message key, for later
           use with "--keys".

       -l filename
       --log=filename
       --log-file=filename
           The filename is to where makepp wrote its log.  It may also be a directory, in which a
           file called .makepp/log or log will be searched.  To read from stdin, you must give -
           as a filename.  When this option is not given, it defaults to the current directory.

           This option can be given multiple times, e.g. for merging all the logs from
           "--traditional-recursive-make".  But it will get the message version information,
           which keeps track of message formats, only from the first file.  So if you feed it log
           files from different version of makepp in the same invocation, output can get a bit
           messed up.

       -n
       --no-indent
           Makepp puts indentation information into the log file to show you what happened
           because of what else.  This option turns indentation off.

       -o filename
       --output=filename
           Write the output to this file, rather than stdout.

       -p
       --prefix
           Prefix every structured message with the string "makepplog: ".  IDEs like Emacs can
           then parse the lines and hyperlink to the mentioned files.

       -t
       --tabulate
           Put each list item on a new line, rather than outputting a line that can easily become
           longer than a screenful.

       -u
       --uniq
       --unique
           Report each found include statement and each scan output only once.

       -V
       --version
           Print out the version number.

EXAMPLES

       If you want to know which file includes which other file, and nothing else:

           makeppclean -r
           makepp                      # Full build to scan all source files.
           makepplog -p '/^INCL$/'

       If you want to format lines with a prefix so Emacs' compilation-mode can parse the lines
       and exclude all scanning related messages:

           makepplog -mp '!/^SCAN/'

       If you want to explore which keys you can exclude or include in the above manners:

           makepplog -kn

ENVIRONMENT

       Makepplog looks at the following environment variable:

       $MAKEPPLOGFLAGS
           Any flags in this environment variable are interpreted as command line options before
           any explicit options.  Quotes are interpreted like in makefiles.
