This is used mainly to distinguish platform-specific build directories and platform-specific built distributions. Typically includes the OS name and version and the architecture (as supplied by 'os.uname()'), although the exact information included depends on the OS; eg. for IRIX the architecture isn't particularly important (IRIX only runs on SGI hardware), but for Linux the kernel version isn't particularly important.

'py_files' is a list of files to compile; any files that don't end in ".py" are silently skipped. 'optimize' must be one of the following: 0 - don't optimize (generate .pyc) 1 - normal optimization (like "python -O") 2 - extra optimization (like "python -OO") If 'force' is true, all files are recompiled regardless of timestamps. The source filename encoded in each bytecode file defaults to the filenames listed in 'py_files'; you can modify these with 'prefix' and 'basedir'. 'prefix' is a string that will be stripped off of each source filename, and 'base_dir' is a directory name that will be prepended (after 'prefix' is stripped). You can supply either or both (or neither) of 'prefix' and 'base_dir', as you wish. If 'dry_run' is true, doesn't actually do anything that would affect the filesystem. Byte-compilation is either done directly in this interpreter process with the standard py_compile module, or indirectly by writing a temporary script and executing it. Normally, you should let 'byte_compile()' figure out to use direct compilation or not (see the source for details). The 'direct' flag is used by the script generated in indirect mode; unless you know what you're doing, leave it set to None. sbyte-compiling is disabled.iiÿÿÿÿ(tmkstemps.py(tmktemps$writing byte-compilation script '%s'tws2from distutils.util import byte_compile files = [ s, s] sŒ byte_compile(files, optimize=%r, force=%r, prefix=%r, base_dir=%r, verbose=%r, dry_run=0, direct=1) is-Ois-OOR}s removing %s(R*iýÿÿÿtctos1invalid prefix: filename %r doesn't start with %rsbyte-compiling %s to %ss%skipping byte-compilation of %s to %sN(!Rtdont_write_bytecodeRRlt __debug__ttempfileRt ImportErrorRŽRRxRtfdopentopentwriteRRFtmaptreprtcloset executabletinsertRR~RCt py_compileR*R"RAREtbasenameRtdebug(tpy_filestoptimizetforceR2tbase_dirR|R}tdirectRt script_fdt script_nameRŽtscripttcmdR*tfiletcfiletdfilet cfile_base((sA/usr/jas/src/cmd/cpython/dist/sys/lib/python2.7/distutils/util.pyt byte_compileWsh"    &      cCs,tj|dƒ}tj|ddƒ}|S(sŒReturn a version of the string escaped for inclusion in an RFC-822 header, by ensuring there are 8 spaces space after each newline. s iRs (RRBRF(theadertlines((sA/usr/jas/src/cmd/cpython/dist/sys/lib/python2.7/distutils/util.pyt rfc822_escapeæs( t__doc__t __revision__RRRR)tdistutils.errorsRtdistutils.dep_utilRtdistutils.spawnRR=RRR>RIRORRRVR_RdRlRfRgRhRiRvR~RŒR®R±(((sA/usr/jas/src/cmd/cpython/dist/sys/lib/python2.7/distutils/util.pyts00 ^       ?  ‹
