This directory contains GNU sed. Please report all bugs and comments to bug-gnu-utils@prep.ai.mit.edu. This sed may run slower than some UN*X seds. This is because it uses the regular-expression routines from Emacs, which are rather complete and powerful, but not as fast as they could be. If you really care about speed, use perl instead. To compile: 1. Type `sh configure'. This shell script attempts to guess correct values for various system-dependent variables used during compilation, and creates the file `Makefile'. This takes a minute or so. If you want to compile in a different directory from the one containing the source code, `cd' to that directory and run `configure' with the option `+srcdir=DIR', where DIR is the directory that contains the source code. The object files and executables will be put in the current directory. This option only works with versions of `make' that support the VPATH variable. `configure' ignores any other arguments you give it. If your system requires unusual options for compilation or linking that `configure' doesn't know about, you can give `configure' initial values for variables by setting them in the environment; in Bourne-compatible shells, you can do that on the command line like this: $ CC='gcc -traditional' LIBS=-lposix sh configure 2. If you want to change the directories where the program will be installed, or the optimization options, edit `Makefile' and change those values. If you have an unusual system that needs special compilation options that `configure' doesn't know about, and you didn't pass them in the environment when running `configure', you should add them to `Makefile' now. Alternately, teach `configure' how to figure out that it is being run on a system where they are needed, and mail the diffs to the address listed at the top of this file so we can include them in the next release. 3. Type `make'. 4. If the program compiles successfully, type `make install' to install it. 5. After you have installed the program, you can remove the binary from the source directory by typing `make clean'. Type `make distclean' if you also want to remove `Makefile', for instance if you are going to recompile sed next on another type of machine.
