NAME

       BJam/MR — Make(1) Redux

SYNOPSIS

       jam  [-a]   [-n]   [-v]   [-d  debug]   [-f  jambase]   [-j  jobs]  [-o
       actionsfile]  [-s var=value]  [-t target]  [target ...]

DESCRIPTION

       BJam is a program construction tool, like make(1).

       BJam  recursively  builds  target  files  from  source   files,   using
       dependency  information  and  updating actions expressed in the Jambase
       file, which is written in bjam’s own interpreted language.  The default
       Jambase  is  compiled  into  bjam and provides a boilerplate for common
       use, relying on a  user-provide  file  "Jamfile"  to  enumerate  actual
       targets and sources.

OPTIONS

       -a        Build all targets anyway, even if they are up-to-date.

       -d n      Enable  cummulative debugging levels from 1 to n. Interesting
                 values are:

                 1

                 Show actions (the default)

                 2

                 Show "quiet" actions and display all action text

                 3

                 Show dependency analysis, and target/source timestamps/paths

                 4

                 Show shell arguments

                 5

                 Show rule invocations and variable expansions

                 6

                 Show directory/header file/archive scans

                 7

                 Show variable settings

                 8

                 Show variable fetches

                 9

                 Show variable manipulation, scanner tokens

       -d +n     Enable debugging level n.

       -d 0      Turn  off  all  debugging  levels.  Only   errors   are   not
                 suppressed.

       -f jambase
                 Read  jambase instead of using the built-in Jambase. Only one
                 -f flag is permitted, but the jambase may explicitly  include
                 other files.

       -j n      Run  up  to n shell commands concurrently (UNIX and NT only).
                 The default is 1.

       -n        Don’t  actually  execute  the  updating   actions,   but   do
                 everything else. This changes the debug level default to -d2.

       -o file   Write the updating actions to the specified file  instead  of
                 running them (or outputting them, as on the Mac).

       -s var=value
                 Set  the  variable  var  to  value,  overriding both internal
                 variables and variables imported from the environment.

       -t target Rebuild target and everything that depends on it, even if  it
                 is up-to-date.

       -v        Print the version of bjam and exit.
