| 3 | # This script is used to configure BusyBox. |
| 4 | # |
| 5 | # It was inspired by the challenge in the original Configure script |
| 6 | # to ``do something better'', combined with the actual need to ``do |
| 7 | # something better'' because the old configure script wasn't flexible |
| 8 | # enough. |
| 9 | # |
| 10 | # Raymond Chen was the original author of Configure. |
| 11 | # Michael Elizabeth Chastain (mec@shout.net) is the current maintainer. |
| 12 | # |
| 13 | # 050793 - use IFS='@' to get around a bug in a pre-version of bash-1.13 |
| 14 | # with an empty IFS. |
| 15 | # |
| 16 | # 030995 (storner@osiris.ping.dk) - added support for tri-state answers, |
| 17 | # for selecting modules to compile. |
| 18 | # |
| 19 | # 180995 Bernhard Kaindl (bkaindl@ping.at) - added dummy functions for |
| 20 | # use with a config.in modified for make menuconfig. |
| 21 | # |
| 22 | # 301195 (boldt@math.ucsb.edu) - added help text support |
| 23 | # |
| 24 | # 281295 Paul Gortmaker - make tri_state functions collapse to boolean |
| 25 | # if module support is not enabled. |
| 26 | # |
| 27 | # 010296 Aaron Ucko (ucko@vax1.rockhurst.edu) - fix int and hex to accept |
| 28 | # arbitrary ranges |
| 29 | # |
| 30 | # 150296 Dick Streefland (dicks@tasking.nl) - report new configuration |
| 31 | # items and ask for a value even when doing a "make oldconfig" |
| 32 | # |
| 33 | # 200396 Tom Dyas (tdyas@eden.rutgers.edu) - when the module option is |
| 34 | # chosen for an item, define the macro <option_name>_MODULE |
| 35 | # |
| 36 | # 090397 Axel Boldt (boldt@math.ucsb.edu) - avoid ? and + in regular |
| 37 | # expressions for GNU expr since version 1.15 and up use \? and \+. |
| 38 | # |
| 39 | # 300397 Phil Blundell (pjb27@cam.ac.uk) - added support for min/max |
| 40 | # arguments to "int", allow dep_tristate to take a list of dependencies |
| 41 | # rather than just one. |
| 42 | # |
| 43 | # 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help |
| 44 | # texts. |
| 45 | # |
| 46 | # 102598 Michael Chastain (mec@shout.net) - put temporary files in |
| 47 | # current directory, not in /tmp. |
| 48 | # |
| 49 | # 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net> |
| 50 | # - Improve the exit message (Jeff Ronne). |
| 51 | # |
| 52 | # 7 October 2000, Ghozlane Toumi, <gtoumi@messel.emse.fr> |
| 53 | # added switches for "random" , "all yes" and "all modules" |
| 54 | # |
