+This package requires flex, bison and qt to compile (actually it's
+possible without qt, but you'll miss most of the fun :) ).
+On most systems a simple 'make' should be enough, if you have qt
+installed in unusual location either set the QTDIR environment variable
+or issue 'make QTDIR=<path>'.
+
+'make install KERNELSRC=<path/to/linux/kernel> should be enough to
+install the package. The path must point to recent kernel sources,
+which will be converted to use this package. With 'make uninstall
+KERNELSRC=...' the package can be removed from the kernel again.
+
+lkc include a SWIG interface file. 'make ruby' builds a extension
+library for ruby in the .ruby dir.
+
+Have fun, Roman

++ WARNING This driver is an older aic7xxx driver and is no longer
++ under active development. Adaptec, Inc. is writing a new driver to
++ take the place of this one, and it is recommended that whenever
++ possible, people should use the new Adaptec written driver instead
++ of this one. This driver will eventually be phased out entirely.
++
++ This is support for the various aic7xxx based Adaptec SCSI
++ controllers. These include the 274x EISA cards; 284x VLB cards;
++ 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
++ motherboard based SCSI controllers from Adaptec. It does not support
++ the AAA-13x RAID controllers from Adaptec, nor will it likely ever
++ support them. It does not support the 2920 cards from Adaptec that
++ use the Future Domain SCSI controller chip. For those cards, you
++ need the "Future Domain 16xx SCSI support" driver.
++
++ In general, if the controller is based on an Adaptec SCSI controller
++ chip from the aic777x series or the aic78xx series, this driver
++ should work. The only exception is the 7810 which is specifically
++ not supported (that's the RAID controller chip on the AAA-13x
++ cards).
++
++ Note that the AHA2920 SCSI host adapter is *not* supported by this
++ driver; choose "Future Domain 16xx SCSI support" instead if you have
++ one of those.
++
++ Information on the configuration options for this controller can be
++ found by checking the help file for each of the available
++ configuration options. You should read
++ <file:drivers/scsi/aic7xxx_old/README.aic7xxx> at a minimum before
++ contacting the maintainer with any questions. The SCSI-HOWTO,
++ available from <http://www.linuxdoc.org/docs.html#howto>, can also
++ be of great help.
++
++ If you want to compile this driver as a module ( = code which can be
++ inserted in and removed from the running kernel whenever you want),
++ say M here and read <file:Documentation/modules.txt>. The module
++ will be called aic7xxx_old.o.

+- WARNING This driver is an older aic7xxx driver and is no longer
+- under active development. Adaptec, Inc. is writing a new driver to
+- take the place of this one, and it is recommended that whenever
+- possible, people should use the new Adaptec written driver instead
+- of this one. This driver will eventually be phased out entirely.
+-
+- This is support for the various aic7xxx based Adaptec SCSI
+- controllers. These include the 274x EISA cards; 284x VLB cards;
+- 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
+- motherboard based SCSI controllers from Adaptec. It does not support
+- the AAA-13x RAID controllers from Adaptec, nor will it likely ever
+- support them. It does not support the 2920 cards from Adaptec that
+- use the Future Domain SCSI controller chip. For those cards, you
+- need the "Future Domain 16xx SCSI support" driver.
+-
+- In general, if the controller is based on an Adaptec SCSI controller
+- chip from the aic777x series or the aic78xx series, this driver
+- should work. The only exception is the 7810 which is specifically
+- not supported (that's the RAID controller chip on the AAA-13x
+- cards).
+-
+- Note that the AHA2920 SCSI host adapter is *not* supported by this
+- driver; choose "Future Domain 16xx SCSI support" instead if you have
+- one of those.
+-
+- Information on the configuration options for this controller can be
+- found by checking the help file for each of the available
+- configuration options. You should read
+- <file:drivers/scsi/aic7xxx_old/README.aic7xxx> at a minimum before
+- contacting the maintainer with any questions. The SCSI-HOWTO,
+- available from <http://www.linuxdoc.org/docs.html#howto>, can also
+- be of great help.
+-
+- If you want to compile this driver as a module ( = code which can be
+- inserted in and removed from the running kernel whenever you want),
+- say M here and read <file:Documentation/modules.txt>. The module
+- will be called aic7xxx_old.o.

+Introduction
+------------
+
+The configuration database is collection of configuration options
+organized in a tree structure:
+
+ +- Code maturity level options
+ | +- Prompt for development and/or incomplete code/drivers
+ +- General setup
+ | +- Networking support
+ | +- System V IPC
+ | +- BSD Process Accounting
+ | +- Sysctl support
+ +- Loadable module support
+ | +- Enable loadable module support
+ | +- Set version information on all module symbols
+ | +- Kernel module loader
+ +- ...
+
+Every entry has its own dependencies. These dependencies are used
+to determine the visible of an entry. Any child entry is only
+visible if its parent entry is also visible.
+
+Menu entries
+------------
+
+A single configuration option is defined like this:
+
+config MODVERSIONS
+ bool "Set version information on all module symbols"
+ depends MODULES
+ help
+ Usually, modules have to be recompiled whenever you switch to a new
+ kernel. ...
+
+Every line starts with a key word and can be followed by multiple arguments.
+"config" starts a new config entry. The following lines define attributes
+for this config option. Attributes can be the type of the config option,
+input prompt, dependencies, help text and default values. A config option
+can be defined multiple times, but every definition can have only a single
+input prompt and the type must not conflict.
+
+Menu dependencies
+-----------------
+
+Dependencies define the visibility of a menu entry. When a dependency
+exprecession evaluates not to 'n', the entry is visible. Additionally
+the dependency limits the input range of tristate choice symbols.
+
+Menu structure
+--------------
+
+The position of a menu entry in the tree is determined in two ways. First
+it can be specified explicitely:
+
+menu "Network device support"
+ depends NET
+
+config NETDEVICES
+ ...
+
+endmenu
+
+All entries within the "menu" ... "endmenu" block become a submenu of
+"Processor type and features". All subentries have the same dependencies
+than the menu entry, e.g. this means the dependency "NET" is added to the
+dependencies of the option NETDEVICES.
+The other way to generate the menu structure is done by analyzing the
+dependencies. If a menu entry somehow depends on the previous entry, it
+can be made a submenu of it.
+
+config MODULES
+ bool "Enable loadable module support"
+
+config MODVERSIONS
+ bool "Set version information on all module symbols"
+ depends MODULES
+
+comment "module support disabled"
+ depends !MODULES
+
+MODVERSIONS directly depends on MODULES, this means it's only visible if
+MODULES is different from 'n'. The comment on the other hand is always
+visible when MODULES it's visible (the dependency of MODULES are part
+of the comment dependencies).
+
+Menu attributes
+---------------
+
+A menu attribute can have a number of attributes. Not all of them are
+applicable everywhere (see spec).
+Input prompt: Every menu entry can have at most one menu entry, which
+is used to display to the user. An input prompt is either defined with
+"prompt" or it can be defined with the type.
+Type definition: Every config option must have a type, known types are
+currently: bool, tristate, string, hex, integer.
+Default value: It's possible to assign a config option a default value.
+This default is always used, when the option wasn't explicitly set by
+the user. This means it's either used as default value for input prompts
+or the value is saved to the kernel configuration. Multiple default
+values can be specified and every one has it's own dependencies. If
+multiple default values are visible, the first defined one is active.
+A default is not limited to a single menu entry, this means the default
+doesn't has to be defined with a input prompt, but it can also be
+overridden by prepend it with another definition.
+Dependencies: Dependencies can be either defined with "depends", then
+there are applied to all attributes of a menu entry, or attribute
+specific dependencies can be defined with "if", which immediately
+follows the attribute.

+1. General Structure
+
+The configuration file describes a series of menu entries. These menu
+entries are organized in a tree structure. The following statements
+start a new menu entry definition (and end a previous menu entry):
+- config
+- choice
+- comment
+- menu
+The following statements are control entries and also end the definition
+of a previous menu entry:
+- source
+- if
+
+2. Dependencies
+
+Every menu entry has dependencies, which define it's visibility in the
+menu structure. What makes these dependencies more difficult is that
+they use three states instead of two, that most programmers are familiar
+with. The additional 'mod' state is needed to describe drivers which
+are not compiled into the kernel, but are compiled as modules, which
+can be loaded at runtime. Nevertheless they should be straigthforward
+to use.
+Dependencies describe in first place the relation between configuration
+symbols and consequently between different parts of the kernel. To
+simplify the verification of the rule base, dependencies must be
+hierarchical, that means no recursive dependencies are allowed. The only
+possible non-hierarchical dependency are exclusions (aka choices), to
+cover typical uses during kernel configuration the semantic of choice
+statements has been extended (see the choice statement below).
+
+This allows to describe the following basic relationships:
+- initialization order of kernel subsystems. That means which other
+ subsystems are required (initialized and working), before a specific
+ subsystem can be initialized itself. This allows above requirement of
+ hierarchical dependencies.
+- mutual exclusions of kernel subsystems. This allows that only a single
+ of multiple possible subsystems is configured into the kernel.
+These are the same relationships, which are reasonably representable
+with cml1, but with this new config syntax it should be possible to
+easily add further relationships and other properties.
+
+The important usage of the dependency information is for generation of
+the menu structure. First it defines whether a symbol or statement is
+visible at all. If the dependency expression evaluates to 'n', the symbol
+is not visible (and is currently also not saved, this BTW corresponds to
+the behavior of xconfig, which is noted as a bug in Documentation/
+kbuild/config-language.txt, that didn't seem to be a problem so far, but
+that has to be considered).
+If a symbol is visible, it defines the possible input range for tristate
+symbols, if the dependency expression evaluates to 'm', a tristate symbol
+can only be set to 'n' or 'm', otherwise also 'y' is possible.
+Finally dependency information is also used to group symbols together.
+If a symbol entry is followed by other symbol entries which depends on
+the first one, the latter entries are associated with the first entry.
+The text config front end uses this information to automatically indent
+the entries, the qt interface creates further submenus. This can reduce
+the amount of explicit menu information required.
+
+syntax:
+
+This is the syntax of dependency expressions:
+
+<expr> ::= <symbol> (1)
+ <symbol> '=' <symbol> (2)
+ <symbol> '!=' <symbol> (3)
+ '(' <expr> ')' (4)
+ '!' <expr> (5)
+ <expr> '||' <expr> (6)
+ <expr> '&&' <expr> (7)
+
+Expressions are listed in decreasing order of precedence. An
+expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 respectively
+for calculations below).
+There are two type of symbols: constant and nonconstant symbols.
+Nonconstant symbols are the most common ones and are defined with the
+'config' statement. Nonconstant symbols consist entirely of alphanumeric
+characters or underscores.
+Constant symbols are only part of expressions. Constant symbols are
+always surrounded by single or double quotes. Within the quote any
+other character is allowed and the quotes can be escaped using '\'.
+Nonconstant symbols which are nowhere defined with 'config' are a
+special case, they behave like constant symbols, so that one can do
+"FOO=123", it usage should restricted to number values (this might
+be enforced later).
+
+expression syntax:
+
+(1) Convert the symbol into an expression. Boolean and tristate symbols
+ are simply converted into the respective expression values. All other
+ symbol types result in 'n'.
+(2) If the values of both symbols are equal, it returns 'y', otherwise 'n'.
+(3) If the values of both symbols are equal, it returns 'n', otherwise 'y'.
+(4) Returns the value of the expression. Used to override precedence.
+(5) Returns the result of (2-/expr/).
+(6) Returns the result of min(/expr/, /expr/).
+(7) Returns the result of max(/expr/, /expr/).
+
+3. "config"
+
+syntax:
+
+ "config" <symbol>
+ <config options>
+
+Defines a new config symbol. A symbol can be defined multiple times as
+long as the symbol type is always the same.
+
+config options:
+
+ "depends" <expr>
+
+defines the visibility and the input range of the config symbol.
+
+ "tristate" <prompt> "if" <expr>
+ "bool" <prompt> "if" <expr>
+ "int" <prompt> "if" <expr>
+ "hex" <prompt> "if" <expr>
+ "string" <prompt> "if" <expr>
+
+defines the type of the symbol and the prompt which is used to request a
+value from the user. Additional constraints for the visibility and the
+input range of the prompt can be defined after an "if" statement. The
+prompt and the "if" statement are optional, but an "if" statement
+without a prompt is not possible.
+
+ "prompt" <prompt> "if" <expr>
+
+same as above, but without defining the type of the symbol. This was
+generated by earlier versions of the converter and will likely
+disappear unless needed otherwise.
+
+ "default" <symbol> "if" <expr>
+
+defines a default value for the config symbol. Unless the config symbol
+was previously set by the user, it will set to this value. This means
+it will be used as default value for above input prompts or if no user
+prompt is visible the config symbol will be saved with this value. If
+multiple default statements are visible only the first is used.
+
+ "help"
+
+defines a help text for this statement. The end of the help text
+is determined by the level indentation, this means it ends at the first
+line which has a smaller indentation than the first line of the help text.
+
+4. "choice"
+
+syntax:
+
+ "choice"
+ <choice options>
+ <choice block>
+ "endchoice"
+
+defines a group of related config statements. There are two types of
+choice statements - bool and tristate.
+
+bool choice: allows only single config statement to be selected and
+set to "y".
+tristate choice: extends the bool choice by also allowing multiple
+config statement to be selected, but in this mode these will only be set
+"m". This can be used if multiple drivers for a single hardware exists
+and only a single driver can be compiled/loaded into the kernel, but all
+drivers can be compiled as modules.
+
+choice options:
+
+ "depends" <expr>
+
+defines the visibility and the input range of the choice.
+
+ "prompt" <prompt>
+
+defines the prompt which is presented to the user.
+
+ <optional>
+
+by default exactly one of the config statements of a bool choice has
+to be selected, this option allows that also no config statement has to
+be selected.
+
+ "default" <symbol>
+
+defines the default choice presented to the user. The prompt must be a
+one of symbols defined within this choice.
+
+ "help"
+
+defines a help text for this choice statement. The end of the help text
+is determined by the level indentation, this means it ends at the first
+line which has a smaller indentation than the first line of the help text.
+
+choice block:
+
+right now only config statements allowed. (It's possible to also allow
+other statements later.)
+
+5. "comment"
+
+syntax:
+
+ "comment" <prompt>
+ <comment options>
+
+defines the prompt which is displayed to the user during the
+configuration process and is also echoes it to the output files during
+output.
+
+comment options:
+
+ "depends" <expr>
+
+defines the visibility of the comment.
+
+6. "menu"
+
+syntax:
+
+ "menu" <prompt>
+ <menu options>
+ <menu block>
+ "endmenu"
+
+menu options:
+
+ "depends" <expr>
+
+defines the visibility of the menu.
+
+menu block:
+
+Any of the basic statements is allowed within a menu block.
+
+7. "if"
+
+syntax:
+
+ "if" <expr>
+ <if block>
+ "endif"
+
+8. "source"
+
+syntax:
+
+ "source" <prompt>
+
+reads the specified configuration file. this is done unconditionally,

+ * Changes by Clifford Wolf (god@clifford.at)
+ *
+ * [ 1998-06-13 ]
+ *
+ * *) A bugfix for the Page-Down problem
+ *
+ * *) Formerly when I used Page Down and Page Up, the cursor would be set
+ * to the first position in the menu box. Now lxdialog is a bit
+ * smarter and works more like other menu systems (just have a look at
+ * it).
+ *
+ * *) Formerly if I selected something my scrolling would be broken because
+ * lxdialog is re-invoked by the Menuconfig shell script, can't
+ * remember the last scrolling position, and just sets it so that the
+ * cursor is at the bottom of the box. Now it writes the temporary file
+ * lxdialog.scrltmp which contains this information. The file is
+ * deleted by lxdialog if the user leaves a submenu or enters a new
+ * one, but it would be nice if Menuconfig could make another "rm -f"
+ * just to be sure. Just try it out - you will recognise a difference!
+ *
+ * [ 1998-06-14 ]
+ *
+ * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ * and menus change their size on the fly.
+ *
+ * *) If for some reason the last scrolling position is not saved by
+ * lxdialog, it sets the scrolling so that the selected item is in the
+ * middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.
