Concatenate all the arguments and make the result a list.
The result is a list whose elements are the elements of all the arguments.
Each argument xmay be a list, vector or string.
The last argument is not copied, just used as the tail of the new list.

Return non-nil if KEY is `equal' to the car of an element of LIST.
The value is actually the first element of LIST whose car equals KEY.

Return non-nil if KEY is `eq' to the car of an element of LIST.
The value is actually the first element of LIST whose car is KEY.
Elements of LIST that are not conses are ignored.

Base64-decode the region between BEG and END.
Return the length of the decoded text.
If the region can't be decoded, signal an error and don't modify the buffer.

Base64-decode STRING and return the result.

Base64-encode the region between BEG and END.
Return the length of the encoded text.
Optional third argument NO-LINE-BREAK means do not break long lines
into shorter lines.

Base64-encode STRING and return the result.
Optional second argument NO-LINE-BREAK means do not break long lines
into shorter lines.

Clear the contents of STRING.
This makes STRING unibyte and may change its length.

Clear hash table TABLE and return it.

Compare the contents of two strings, converting to multibyte if needed.
In string STR1, skip the first START1 characters and stop at END1.
In string STR2, skip the first START2 characters and stop at END2.
END1 and END2 default to the full lengths of the respective strings.

Case is significant in this comparison if IGNORE-CASE is nil.
Unibyte strings are converted to multibyte for comparison.

The value is t if the strings (or specified portions) match.
If string STR1 is less, the value is a negative number N;
  - 1 - N is the number of characters that match at the beginning.
If string STR1 is greater, the value is a positive number N;
  N - 1 is the number of characters that match at the beginning.

Concatenate all the arguments and make the result a string.
The result is a string whose elements are the elements of all the arguments.
Each argument may be a string or a list or vector of characters (integers).

Return a copy of ALIST.
This is an alist which represents the same mapping from objects to objects,
but does not share the alist structure with ALIST.
The objects mapped (cars and cdrs of elements of the alist)
are shared, however.
Elements of ALIST that are not conses are also shared.

Return a copy of hash table TABLE.

Return a copy of a list, vector, string or char-table.
The elements of a list or vector are not copied; they are shared
with the original.

Define a new hash table test with name NAME, a symbol.

In hash tables created with NAME specified as test, use TEST to
compare keys, and HASH for computing hash codes of keys.

TEST must be a function taking two arguments and returning non-nil if
both arguments are the same.  HASH must be a function taking one
argument and return an integer that is the hash code of the argument.
Hash code computation should use the whole value range of integers,
including negative integers.

Delete by side effect any occurrences of ELT as a member of SEQ.
SEQ must be a list, a vector, or a string.
The modified SEQ is returned.  Comparison is done with `equal'.
If SEQ is not a list, or the first member of SEQ is ELT, deleting it
is not a side effect; it is simply using a different sequence.
Therefore, write `(setq foo (delete element foo))'
to be sure of changing the value of `foo'.

Delete by side effect any occurrences of ELT as a member of LIST.
The modified LIST is returned.  Comparison is done with `eq'.
If the first member of LIST is ELT, there is no way to remove it by side effect;
therefore, write `(setq foo (delq element foo))'
to be sure of changing the value of `foo'.

Return element of SEQUENCE at index N.

Return t if the two args are the same Lisp object.
Floating-point numbers of equal value are `eql', but they may not be `eq'.

Return t if two Lisp objects have similar structure and contents.
They must have the same data type.
Conses are compared by comparing the cars and the cdrs.
Vectors and strings are compared element by element.
Numbers are compared by value, but integers cannot equal floats.
 (Use `=' if you want integers and floats to be able to be equal.)
Symbols must match exactly.

Return t if two Lisp objects have similar structure and contents.
This is like `equal' except that it compares the text properties
of strings.  (`equal' ignores text properties.)

Return t if FEATURE is present in this Emacs.

Use this to conditionalize execution of lisp code based on the
presence or absence of Emacs or environment extensions.
Use `provide' to declare that a feature is available.  This function
looks at the value of the variable `features'.  The optional argument
SUBFEATURE can be used to check a specific subfeature of FEATURE.

Store each element of ARRAY with ITEM.
ARRAY is a vector, string, char-table, or bool-vector.

Return the value of SYMBOL's PROPNAME property.
This is the last value stored with `(put SYMBOL PROPNAME VALUE)'.

Look up KEY in TABLE and return its associated value.
If KEY is not found, return DFLT which defaults to nil.

Return the number of elements in TABLE.

Return t if OBJ is a Lisp hash table object.

Return the current rehash size of TABLE.

Return the current rehash threshold of TABLE.

Return the size of TABLE.
The size can be used as an argument to `make-hash-table' to create
a hash table than can hold as many elements as TABLE holds
without need for resizing.

Return the test TABLE uses.

Return the weakness of TABLE.

Return the argument unchanged.

Extract a value from a property list, comparing with `equal'.
PLIST is a property list, which is a list of the form
(PROP1 VALUE1 PROP2 VALUE2...).  This function returns the value
corresponding to the given PROP, or nil if PROP is not
one of the properties on the list.

Change value in PLIST of PROP to VAL, comparing with `equal'.
PLIST is a property list, which is a list of the form
(PROP1 VALUE1 PROP2 VALUE2 ...).  PROP and VAL are any objects.
If PROP is already a property on the list, its value is set to VAL,
otherwise the new PROP VAL pair is added.  The new plist is returned;
use `(setq x (lax-plist-put x prop val))' to be sure to use the new value.
The PLIST is modified by side effects.

Return the length of vector, list or string SEQUENCE.
A byte-code function object is also allowed.
If the string contains multibyte characters, this is not necessarily
the number of bytes in the string; it is the number of characters.
To get the number of bytes, use `string-bytes'.

Return list of 1 minute, 5 minute and 15 minute load averages.

Each of the three load averages is multiplied by 100, then converted
to integer.

When USE-FLOATS is non-nil, floats will be used instead of integers.
These floats are not multiplied by 100.

If the 5-minute or 15-minute load averages are not available, return a
shortened list, containing only those averages which are available.

An error is thrown if the load average can't be obtained.  In some
cases making it work would require Emacs being installed setuid or
setgid so that it can read kernel information, and that usually isn't
advisable.

Access locale data ITEM for the current C locale, if available.
ITEM should be one of the following:

`codeset', returning the character set as a string (locale item CODESET);

`days', returning a 7-element vector of day names (locale items DAY_n);

`months', returning a 12-element vector of month names (locale items MON_n);

`paper', returning a list (WIDTH HEIGHT) for the default paper size,
  both measured in millimeters (locale items PAPER_WIDTH, PAPER_HEIGHT).

If the system can't provide such information through a call to
`nl_langinfo', or if ITEM isn't from the list above, return nil.

See also Info node `(libc)Locales'.

The data read from the system are decoded using `locale-coding-system'.

Create and return a new hash table.

Arguments are specified as keyword/argument pairs.  The following
arguments are defined:

:test TEST -- TEST must be a symbol that specifies how to compare
keys.  Default is `eql'.  Predefined are the tests `eq', `eql', and
`equal'.  User-supplied test and hash functions can be specified via
`define-hash-table-test'.

:size SIZE -- A hint as to how many elements will be put in the table.
Default is 65.

:rehash-size REHASH-SIZE - Indicates how to expand the table when it
fills up.  If REHASH-SIZE is an integer, increase the size by that
amount.  If it is a float, it must be > 1.0, and the new size is the
old size multiplied by that factor.  Default is 1.5.

:rehash-threshold THRESHOLD -- THRESHOLD must a float > 0, and <= 1.0.
Resize the hash table when the ratio (number of entries / table size)
is greater than or equal to THRESHOLD.  Default is 0.8.

:weakness WEAK -- WEAK must be one of nil, t, `key', `value',
`key-or-value', or `key-and-value'.  If WEAK is not nil, the table
returned is a weak table.  Key/value pairs are removed from a weak
hash table when there are no non-weak references pointing to their
key, value, one of key or value, or both key and value, depending on
WEAK.  WEAK t is equivalent to `key-and-value'.  Default value of WEAK
is nil.

Apply FUNCTION to each element of SEQUENCE for side effects only.
Unlike `mapcar', don't accumulate the results.  Return SEQUENCE.
SEQUENCE may be a list, a vector, a bool-vector, or a string.

Apply FUNCTION to each element of SEQUENCE, and make a list of the results.
The result is a list just as long as SEQUENCE.
SEQUENCE may be a list, a vector, a bool-vector, or a string.

Apply FUNCTION to each element of SEQUENCE, and concat the results as strings.
In between each pair of results, stick in SEPARATOR.  Thus, " " as
SEPARATOR results in spaces between the values returned by FUNCTION.
SEQUENCE may be a list, a vector, a bool-vector, or a string.

Call FUNCTION for all entries in hash table TABLE.
FUNCTION is called with two arguments, KEY and VALUE.

Return MD5 message digest of OBJECT, a buffer or string.

A message digest is a cryptographic checksum of a document, and the
algorithm to calculate it is defined in RFC 1321.

The two optional arguments START and END are character positions
specifying for which part of OBJECT the message digest should be
computed.  If nil or omitted, the digest is computed for the whole
OBJECT.

The MD5 message digest is computed from the result of encoding the
text in a coding system, not directly from the internal Emacs form of
the text.  The optional fourth argument CODING-SYSTEM specifies which
coding system to encode the text with.  It should be the same coding
system that you used or will use when actually writing the text into a
file.

If CODING-SYSTEM is nil or omitted, the default depends on OBJECT.  If
OBJECT is a buffer, the default for CODING-SYSTEM is whatever coding
system would be chosen by default for writing this text into a file.

If OBJECT is a string, the most preferred coding system (see the
command `prefer-coding-system') is used.

If NOERROR is non-nil, silently assume the `raw-text' coding if the
guesswork fails.  Normally, an error is signaled in such case.

Return non-nil if ELT is an element of LIST.  Comparison done with `equal'.
The value is actually the tail of LIST whose car is ELT.

Return non-nil if ELT is an element of LIST.  Comparison done with `eq'.
The value is actually the tail of LIST whose car is ELT.

Return non-nil if ELT is an element of LIST.  Comparison done with `eql'.
The value is actually the tail of LIST whose car is ELT.

Concatenate any number of lists by altering them.
Only the last argument is not altered, and need not be a list.

Reverse LIST by modifying cdr pointers.
Return the reversed list.

Return the Nth element of LIST.
N counts from zero.  If LIST is not that long, nil is returned.

Take cdr N times on LIST, return the result.

Extract a value from a property list.
PLIST is a property list, which is a list of the form
(PROP1 VALUE1 PROP2 VALUE2...).  This function returns the value
corresponding to the given PROP, or nil if PROP is not one of the
properties on the list.  This function never signals an error.

Return non-nil if PLIST has the property PROP.
PLIST is a property list, which is a list of the form
(PROP1 VALUE1 PROP2 VALUE2 ...).  PROP is a symbol.
Unlike `plist-get', this allows you to distinguish between a missing
property and a property with the value nil.
The value is actually the tail of PLIST whose car is PROP.

Change value in PLIST of PROP to VAL.
PLIST is a property list, which is a list of the form
(PROP1 VALUE1 PROP2 VALUE2 ...).  PROP is a symbol and VAL is any object.
If PROP is already a property on the list, its value is set to VAL,
otherwise the new PROP VAL pair is added.  The new plist is returned;
use `(setq x (plist-put x prop val))' to be sure to use the new value.
The PLIST is modified by side effects.

Announce that FEATURE is a feature of the current Emacs.
The optional argument SUBFEATURES should be a list of symbols listing
particular subfeatures supported in this version of FEATURE.

Store SYMBOL's PROPNAME property with value VALUE.
It can be retrieved with `(get SYMBOL PROPNAME)'.

Associate KEY with VALUE in hash table TABLE.
If KEY is already present in table, replace its current value with
VALUE.  In any case, return VALUE.

Return a pseudo-random number.
All integers representable in Lisp are equally likely.
  On most systems, this is 29 bits' worth.
With positive integer LIMIT, return random number in interval [0,LIMIT).
With argument t, set the random number seed from the current time and pid.
Other values of LIMIT are ignored.

Return non-nil if KEY is `equal' to the cdr of an element of LIST.
The value is actually the first element of LIST whose cdr equals KEY.

Return non-nil if KEY is `eq' to the cdr of an element of LIST.
The value is actually the first element of LIST whose cdr is KEY.

Remove KEY from TABLE.

If feature FEATURE is not loaded, load it from FILENAME.
If FEATURE is not a member of the list `features', then the feature
is not loaded; so load the file FILENAME.
If FILENAME is omitted, the printname of FEATURE is used as the file name,
and `load' will try to load this name appended with the suffix `.elc' or
`.el', in that order.  The name without appended suffix will not be used.
See `get-load-suffixes' for the complete list of suffixes.
If the optional third argument NOERROR is non-nil,
then return nil if the file is not found instead of signaling an error.
Normally the return value is FEATURE.
The normal messages at start and end of loading FILENAME are suppressed.

Reverse LIST, copying.  Return the reversed list.
See also the function `nreverse', which is used more often.

Return the length of a list, but avoid error or infinite loop.
This function never gets an error.  If LIST is not really a list,
it returns 0.  If LIST is circular, it returns a finite value
which is at least the number of distinct elements.

Return the secure hash of OBJECT, a buffer or string.
ALGORITHM is a symbol specifying the hash to use:
md5, sha1, sha224, sha256, sha384 or sha512.

The two optional arguments START and END are positions specifying for
which part of OBJECT to compute the hash.  If nil or omitted, uses the
whole OBJECT.

If BINARY is non-nil, returns a string in binary form.

Sort LIST, stably, comparing elements using PREDICATE.
Returns the sorted list.  LIST is modified by side effects.
PREDICATE is called with two elements of LIST, and should return non-nil
if the first element should sort before the second.

Return a multibyte string with the same individual bytes as STRING.
If STRING is multibyte, the result is STRING itself.
Otherwise it is a newly created string, with no text properties.

If STRING is unibyte and contains an individual 8-bit byte (i.e. not
part of a correct utf-8 sequence), it is converted to the corresponding
multibyte character of charset `eight-bit'.
See also `string-to-multibyte'.

Beware, this often doesn't really do what you think it does.
It is similar to (decode-coding-string STRING 'utf-8-emacs).
If you're not sure, whether to use `string-as-multibyte' or
`string-to-multibyte', use `string-to-multibyte'.

Return a unibyte string with the same individual bytes as STRING.
If STRING is unibyte, the result is STRING itself.
Otherwise it is a newly created string, with no text properties.
If STRING is multibyte and contains a character of charset
`eight-bit', it is converted to the corresponding single byte.

Return the number of bytes in STRING.
If STRING is multibyte, this may be greater than the length of STRING.

Return t if two strings have identical contents.
Case is significant, but text properties are ignored.
Symbols are also allowed; their print names are used instead.

Return t if first arg string is less than second in lexicographic order.
Case is significant.
Symbols are also allowed; their print names are used instead.

Return the multibyte equivalent of STRING.
If STRING is unibyte and contains non-ASCII characters, the function
`unibyte-char-to-multibyte' is used to convert each unibyte character
to a multibyte character.  In this case, the returned string is a
newly created string with no text properties.  If STRING is multibyte
or entirely ASCII, it is returned unchanged.  In particular, when
STRING is unibyte and entirely ASCII, the returned string is unibyte.
(When the characters are all ASCII, Emacs primitives will treat the
string the same way whether it is unibyte or multibyte.)

Return the unibyte equivalent of STRING.
Multibyte character codes are converted to unibyte according to
`nonascii-translation-table' or, if that is nil, `nonascii-insert-offset'.
If the lookup in the translation table fails, this function takes just
the low 8 bits of each character.

Return a multibyte string with the same individual chars as STRING.
If STRING is multibyte, the result is STRING itself.
Otherwise it is a newly created string, with no text properties.

If STRING is unibyte and contains an 8-bit byte, it is converted to
the corresponding multibyte character of charset `eight-bit'.

This differs from `string-as-multibyte' by converting each byte of a correct
utf-8 sequence to an eight-bit character, not just bytes that don't form a
correct sequence.

Return a unibyte string with the same individual chars as STRING.
If STRING is unibyte, the result is STRING itself.
Otherwise it is a newly created string, with no text properties,
where each `eight-bit' character is converted to the corresponding byte.
If STRING contains a non-ASCII, non-`eight-bit' character,
an error is signaled.

Return a new string whose contents are a substring of STRING.
The returned string consists of the characters between index FROM
(inclusive) and index TO (exclusive) of STRING.  FROM and TO are
zero-indexed: 0 means the first character of STRING.  Negative values
are counted from the end of STRING.  If TO is nil, the substring runs
to the end of STRING.

The STRING argument may also be a vector.  In that case, the return
value is a new vector that contains the elements between index FROM
(inclusive) and index TO (exclusive) of that vector argument.

Return a substring of STRING, without text properties.
It starts at index FROM and ends before TO.
TO may be nil or omitted; then the substring runs to the end of STRING.
If FROM is nil or omitted, the substring starts at the beginning of STRING.
If FROM or TO is negative, it counts from the end.

With one argument, just copy STRING without its properties.

Compute a hash code for OBJ and return it as integer.

Concatenate all the arguments and make the result a vector.
The result is a vector whose elements are the elements of all the arguments.
Each argument may be a list, vector or string.

Apply the value of WIDGET's PROPERTY to the widget itself.
ARGS are passed as extra arguments to the function.

In WIDGET, get the value of PROPERTY.
The value could either be specified when the widget was created, or
later with `widget-put'.

In WIDGET, set PROPERTY to VALUE.
The value can later be retrieved with `widget-get'.

Ask user a yes-or-no question.  Return t if answer is yes.
PROMPT is the string to display to ask the question.  It should end in
a space; `yes-or-no-p' adds "(yes or no) " to it.

The user must confirm the answer with RET, and can edit it until it
has been confirmed.

Under a windowing system a dialog box will be used if `last-nonmenu-event'
is nil, and `use-dialog-box' is non-nil.
