Bash is free software, distributed under the terms of the [GNU] General Public License as published by the Free Software Foundation, version 3 of the License (or any later version). For more information, see the file COPYING. A number of frequently-asked questions are answered in the file `doc/FAQ'. To compile Bash, type `./configure', then `make'. Bash auto-configures the build process, so no further intervention should be necessary. Bash builds with `gcc' by default if it is available. If you want to use `cc' instead, type CC=cc ./configure if you are using a Bourne-style shell. If you are not, the following may work: env CC=cc ./configure Read the file INSTALL in this directory for more information about how to customize and control the build process. The file NOTES contains platform-specific installation and configuration information. If you are a csh user and wish to convert your csh aliases to Bash aliases, you may wish to use the script `examples/misc/alias-conv.sh' as a starting point. The script `examples/misc/cshtobash' is a more ambitious script that attempts to do a more complete job.
