`Pf9' is a port of some libraries and programs from `Plan9 fromUser Space' (http://www.swtch.com/plan9port/) to Windowsusing the MinGW compiler. A lot of files are used withoutmodification, some need only slight adaptions. The actual portinghas been done in lib9/mingw and libthread/mingw.c, withhelp of ideas from inferno and 9pm. See LICENSE file for which licenses apply to the source files. For a list of ported programs see DIRS and TARG definitionsin src/cmd/mkfile. For a list of ported libraries see src/lib*. Status of somelibraries: 	libthread: works mostly, daemonizing works not 	libdraw:	works basically, tested with tcolors, acme		and sam. Events have not been ported, so only		programs using the thread-based mouse		interface will run.  Status of the support of various concepts: Pipes	Implemented using Named Pipes. Unix Sockets	Implemented using Named Pipes. You can use the same	addresses as in plan9port, e.g. unix!/tmp/acme. Internet Sockets	Implemented using Winsock. Unicode	All programs get UTF-8 encoded streams on stdin, UTF-8	encoded environment and command line arguments. Console support	Reading from the console input and writing to the console	screen buffer is supported transparently. A "cat > file" from	the Windows console will produce UTF-8 characters, regardless	of which codepage is installed. 	You can also use the history feature of the console window without	extra support in programs. Because the mkfile system's structure has been derived from Plan9, youcan compile the libs and sources for Linux and MinGW in a similar way:On Linux, to compile for the MinGW, run 	cd src	objtype=mingw	mk  Copy identical files from Plan9port--------------------------- A lot of files are used from plan9port without change. They are not distributedalong with pf9. You should have a plan9port distribution installed, and thePLAN9 variable set. You can run 	mk pop		- to populate the source directory with identical					source files from p9p 	mk rm		... remove identical source files; this undos the				effect of `mk pop' 	mk tkdiff		... to get a list of tkdiff commands you can click at in rc to				explore the differences between p9p and pf9 	mk eqdiff		... like `mk tkdiff', but this time a list showing on which				files an ed script has been run. Some files will be modified slightly after copying from plan9port. Thisis done using one ed script per file.  How to build for mingw-------------------Download Plan9Port plan9port-20140306.tgz, sam-editor. If not have mingw32, download and install i686-w64-mingw32. Example for GNU/Linux Ubuntu: 'sudo apt-get mingw-w64' Mingw32 need for compile the sam-editor and other warez for Windows OS. 		# cd ~/		# wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/plan9port/plan9port-20140306.tgz		# tar -zxvf plan9port-20140306.tgz		# sudo mv plan9port /usr/local/plan9 *if need # chmod -R u+x /usr/local/plan9		 		# cd /usr/local/plan9		# ./INSTALL		# cd ~/		# hg clone https://bitbucket.org/jubei85/sam-editor/		# sudo mv sam-editor /usr/local/pf9 *if need # chmod -R u+x /usr/local/pf9 		# cd /usr/local/pf9        # cputype=lin386 export cputype        # objtype=mingw export objtype		# PF9=/usr/local/pf9 export PF9        # PLAN9=/usr/local/plan9 export PLAN9        # PATH=/usr/local/pf9/lin386/bin:$PATH export PATH        # PATH=/usr/local/pf9/linux/bin:$PATH export PATH        # PATH=$PATH:$PLAN9/bin export PATH *if need configure file /$PF9/mingw/configure 		# ./misc/enterpf9		# mk pop		# cd src		# mk		# mk install		All binary files for windos there /$PF9/mingw/bin, enjoy!				  Run it----- 	FIXME		This should be enough to get it work. Now you might generate the	lookman index from a shell prompt, which is a good test of some	of the functionality: 		$ rc		% cd $PF9/sys/man		% ./mkindex  Debugging-------- Define FDTDEBUG=2 to get debug output from the file descriptor layer.
