does not trigger if the character before such a carriage-return
is not a whitespace (not enabled by default).
+core.fsyncobjectfiles::
+ This boolean will enable 'fsync()' when writing object files.
++
+This is a total waste of time and effort on a filesystem that orders
+data writes properly, but can be useful for filesystems that do not use
+journalling (traditional UNIX filesystems) or that only journal metadata
+and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
+
alias.*::
Command aliases for the linkgit:git[1] command wrapper - e.g.
after defining "alias.last = cat-file commit HEAD", the invocation
relative to the repository root (this was the default for git
prior to v1.5.4).
+status.showUntrackedFiles::
+ By default, linkgit:git-status[1] and linkgit:git-commit[1] show
+ files which are not currently tracked by Git. Directories which
+ contain only untracked files, are shown with the directory name
+ only. Showing untracked files means that Git needs to lstat() all
+ all the files in the whole repository, which might be slow on some
+ systems. So, this variable controls how the commands displays
+ the untracked files. Possible values are:
++
+--
+ - 'no' - Show no untracked files
+ - 'normal' - Shows untracked files and directories
+ - 'all' - Shows also individual files in untracked directories.
+--
++
+If this variable is not specified, it defaults to 'normal'.
+This variable can be overridden with the -u|--untracked-files option
+of linkgit:git-status[1] and linkgit:git-commit[1].
+
tar.umask::
This variable can be used to restrict the permission bits of
tar archive entries. The default is 0002, which turns off the

---untracked-files::
- Show all untracked files, also those in uninteresting

+-u[<mode>]::
+--untracked-files[=<mode>]::
+ Show untracked files (Default: 'all').
++
+The mode parameter is optional, and is used to specify
+the handling of untracked files. The possible options are:
++
+--
+ - 'no' - Show no untracked files
+ - 'normal' - Shows untracked files and directories
+ - 'all' - Also shows individual files in untracked directories.

-v::
--verbose::
unsigned, with 'verbatim', they will be silently exported
and with 'warn', they will be exported, but you will see a warning.
+--export-marks=<file>::
+ Dumps the internal marks table to <file> when complete.
+ Marks are written one per line as `:markid SHA-1`. Only marks
+ for revisions are dumped; marks for blobs are ignored.
+ Backends can use this file to validate imports after they
+ have been completed, or to save the marks table across
+ incremental runs. As <file> is only opened and truncated
+ at completion, the same path can also be safely given to
+ \--import-marks.
+
+--import-marks=<file>::
+ Before processing any input, load the marks specified in
+ <file>. The input file must exist, must be readable, and
+ must use the same format as produced by \--export-marks.
++
+Any commits that have already been marked will not be exported again.
+If the backend uses a similar \--import-marks file, this allows for
+incremental bidirectional exporting of the repository by keeping the
+marks the same across runs.

`git-init` is run, a handful example hooks are copied in the
`hooks` directory of the new repository, but by default they are
-all disabled. To enable a hook, make it executable with `chmod +x`.
+all disabled. To enable a hook, rename it by removing its `.sample`
+suffix.
This document describes the currently defined hooks.
parse-options API
=================
-Talk about <parse-options.h>
+The parse-options API is used to parse and massage options in git
+and to provide a usage help with consistent look.
-(Pierre)
+Basics
+------
+
+The argument vector `argv[]` may usually contain mandatory or optional
+'non-option arguments', e.g. a filename or a branch, and 'options'.
+Options are optional arguments that start with a dash and
+that allow to change the behavior of a command.
+
+* There are basically three types of options:
+ 'boolean' options,
+ options with (mandatory) 'arguments' and
+ options with 'optional arguments'
+ (i.e. a boolean option that can be adjusted).
+
+* There are basically two forms of options:
+ 'Short options' consist of one dash (`-`) and one alphanumeric
+ character.
+ 'Long options' begin with two dashes (`\--`) and some
+ alphanumeric characters.
+
+* Options are case-sensitive.
+ Please define 'lower-case long options' only.
+
+The parse-options API allows:
+
+* 'sticked' and 'separate form' of options with arguments.
+ `-oArg` is sticked, `-o Arg` is separate form.
+ `\--option=Arg` is sticked, `\--option Arg` is separate form.
+
+* Long options may be 'abbreviated', as long as the abbreviation
+ is unambiguous.
+
+* Short options may be bundled, e.g. `-a -b` can be specified as `-ab`.
+
+* Boolean long options can be 'negated' (or 'unset') by prepending
+ `no-`, e.g. `\--no-abbrev` instead of `\--abbrev`.
+
+* Options and non-option arguments can clearly be separated using the `\--`
+ option, e.g. `-a -b \--option \-- \--this-is-a-file` indicates that
+ `\--this-is-a-file` must not be processed as an option.
+
+Steps to parse options
+----------------------
+
+. `#include "parse-options.h"`
+
+. define a NULL-terminated
+ `static const char * const builtin_foo_usage[]` array
+ containing alternative usage strings
+
+. define `builtin_foo_options` array as described below
+ in section 'Data Structure'.
+
+. in `cmd_foo(int argc, const char **argv, const char *prefix)`
+ call
+
+ argc = parse_options(argc, argv, builtin_foo_options, builtin_foo_usage, flags);
++
+`parse_options()` will filter out the processed options of `argv[]` and leave the
+non-option arguments in `argv[]`.
+`argc` is updated appropriately because of the assignment.
++
+Flags are the bitwise-or of:
+
+`PARSE_OPT_KEEP_DASHDASH`::
+ Keep the `\--` that usually separates options from
+ non-option arguments.
+
+`PARSE_OPT_STOP_AT_NON_OPTION`::
+ Usually the whole argument vector is massaged and reordered.
+ Using this flag, processing is stopped at the first non-option
+ argument.
+
+Data Structure
+--------------
+
+The main data structure is an array of the `option` struct,
+say `static struct option builtin_add_options[]`.
+There are some macros to easily define options:
+
+`OPT__ABBREV(&int_var)`::
+ Add `\--abbrev[=<n>]`.
+
+`OPT__DRY_RUN(&int_var)`::
+ Add `-n, \--dry-run`.
+
+`OPT__QUIET(&int_var)`::
+ Add `-q, \--quiet`.
+
+`OPT__VERBOSE(&int_var)`::
+ Add `-v, \--verbose`.
+
+`OPT_GROUP(description)`::
+ Start an option group. `description` is a short string that
+ describes the group or an empty string.
+ Start the description with an upper-case letter.
+
+`OPT_BOOLEAN(short, long, &int_var, description)`::
+ Introduce a boolean option.
+ `int_var` is incremented on each use.
+
+`OPT_BIT(short, long, &int_var, description, mask)`::
+ Introduce a boolean option.
+ If used, `int_var` is bitwise-ored with `mask`.
+
+`OPT_SET_INT(short, long, &int_var, description, integer)`::
+ Introduce a boolean option.
+ If used, set `int_var` to `integer`.
+
+`OPT_SET_PTR(short, long, &ptr_var, description, ptr)`::
+ Introduce a boolean option.
+ If used, set `ptr_var` to `ptr`.
+
+`OPT_STRING(short, long, &str_var, arg_str, description)`::
+ Introduce an option with string argument.
+ The string argument is put into `str_var`.
+
+`OPT_INTEGER(short, long, &int_var, description)`::
+ Introduce an option with integer argument.
+ The integer is put into `int_var`.
+
+`OPT_DATE(short, long, &int_var, description)`::
+ Introduce an option with date argument, see `approxidate()`.
+ The timestamp is put into `int_var`.
+
+`OPT_CALLBACK(short, long, &var, arg_str, description, func_ptr)`::
+ Introduce an option with argument.
+ The argument will be fed into the function given by `func_ptr`
+ and the result will be put into `var`.
+ See 'Option Callbacks' below for a more elaborate description.
+
+`OPT_ARGUMENT(long, description)`::
+ Introduce a long-option argument that will be kept in `argv[]`.
+
+
+The last element of the array must be `OPT_END()`.
+
+If not stated otherwise, interpret the arguments as follows:
+
+* `short` is a character for the short option
+ (e.g. `\'e\'` for `-e`, use `0` to omit),
+
+* `long` is a string for the long option
+ (e.g. `"example"` for `\--example`, use `NULL` to omit),
+
+* `int_var` is an integer variable,
+
+* `str_var` is a string variable (`char *`),
+
+* `arg_str` is the string that is shown as argument
+ (e.g. `"branch"` will result in `<branch>`).
+ If set to `NULL`, three dots (`...`) will be displayed.
+
+* `description` is a short string to describe the effect of the option.
+ It shall begin with a lower-case letter and a full stop (`.`) shall be
+ omitted at the end.
+
+Option Callbacks
+----------------
+
+The function must be defined in this form:
+
+ int func(const struct option *opt, const char *arg, int unset)
+
+The callback mechanism is as follows:
+
+* Inside `funct`, the only interesting member of the structure
+ given by `opt` is the void pointer `opt->value`.
+ `\*opt->value` will be the value that is saved into `var`, if you
+ use `OPT_CALLBACK()`.
+ For example, do `*(unsigned long *)opt->value = 42;` to get 42
+ into an `unsigned long` variable.
+
+* Return value `0` indicates success and non-zero return
+ value will invoke `usage_with_options()` and, thus, die.
+
+* If the user negates the option, `arg` is `NULL` and `unset` is 1.
+
+Sophisticated option parsing
+----------------------------
+
+If you need, for example, option callbacks with optional arguments
+or without arguments at all, or if you need other special cases,
+that are not handled by the macros above, you need to specify the
+members of the `option` structure manually.
+
+This is not covered in this document, but well documented
+in `parse-options.h` itself.
+
+Examples
+--------
+
+See `test-parse-options.c` and
+`builtin-add.c`,
+`builtin-clone.c`,
+`builtin-commit.c`,
+`builtin-fetch.c`,
+`builtin-fsck.c`,
+`builtin-rm.c`
+for real-world examples.

-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
- merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
- it is deleted. If you need to build on top of it to correct
- earlier mistakes, a new topic branch is created by forking at
- the tip of the "master". This is not strictly necessary, but
- it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
- branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next". Young
- topic branches can have stupid mistakes you would rather
- clean up before publishing, and things that have not been
- merged into other branches can be easily rebased without
- affecting other people. But once it is published, you would
- not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
- Then you can delete it. More importantly, you should not
- build on top of it -- other people may already want to
- change things related to the topic as patches against your
- "master", so if you need further changes, it is better to
- fork the topic (perhaps with the same name) afresh from the
- tip of "master".
-
-Let's look at this example:
-
- o---o---o---o---o---o---o---o---o---o "next"
- / / / /
- / a---a---b A / /
- / / / /
- / / c---c---c---c B /
- / / / \ /
- / / / b---b C \ /
- / / / / \ /
- ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished. It has been fully merged up to "master" and "next",
- and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
- git-rev-list ^master ^topic next
- git-rev-list ^master next
-
- if these match, topic has not merged in next at all.
-
-To compute (2):
-
- git-rev-list master..topic
-
- if this is empty, it is fully merged to "master".
