Gcal 3.01

[Top] [Contents] [Index] [ ? ]

Footnotes

(1)

I.e. no need to search for calendar information in the net so phone and Internet Service Provider (ISP) costs are reduced, and furthermore, neither searching for such information in books or data files nor the need to use several other software which altogether do what Gcal actually also does.

(2)

The "General Public License" of the Free Software Foundation.

(3)

Inclusive or exclusive.

(4)

Future years.

(5)

Past years.

(6)

This is an operating system program which interprets and runs given command lines.

(7)

Inclusive `%date' and `@file'.

(8)

Unless they take an argument.

(9)

See the standard manual pages for less, more and pg.

(10)

See the standard manual pages for Termcap.

(11)

Either 23 or 24 lines, and 80 columns.

(12)

This means, sent to another device.

(13)

This means, used as an input data stream for another program.

(14)

This means with a leading and a trailing blank.

(15)

See the standard manual pages for mail.

(16)

ISO is the abbreviation of International Organization for Standardization.

(17)

Similar the BSD-cal program.

(18)

The time which is set as system time in the computer's clock.

(19)

The automatical conversion into the according Julian date is always done if the actual system date, that is based on the Gregorian calendar, is before the date of the Gregorian Reformation.

(20)

But GCAL_DATE_FORMAT is only used in case no `--date-format=de|us|gb|text' option is given.

(21)

Except the date variable e which is internally reserved for the Easter Sunday's date, so it cannot be assigned or operated therefore. And except the date variable t which is internally reserved for today's date, so it likewise cannot be assigned or operated.

(22)

Or another global date variable name which is already defined, but no date given in the `e|t|dvar[+|-]n[www]', `mmwwwn', or the `*d|wn[www]' format.

(23)

Refraction is an optical phenomenon caused by the Earth's atmosphere, which leads to an apparent raising of the location of a celestial body. The amount of refraction increases with growing air pressure and sinking temperature and vice-versa.

(24)

Correct, the `--time-offset' option has multiple modes of operation that are depending on the context of its use!

(25)

Except Gcal's line break-up characters `~' and `^', so you have to use `\~' and `\\^' in the pattern argument if you want to search texts which contain these characters.

(26)

This means, exclusive the `--include-today' option respectively `d' modifier, the `--list-mode' option or the `l' modifier, and the `--leap-day=february|march' option.

(27)

Respectively their according long-style options.

(28)

Or their according alias names, like `--today', `--tomorrow'....

(29)

Or their according long-style options.

(30)

RC_GROUP_SEP "" == empty line only.

(31)

Only if the `--alternative-format' option or the `A' modifier is not given.

(32)

The 29th February.

(33)

That is either the 51st, 52nd or 53rd Sunday.

(34)

That is either the 51st, 52nd or 53rd Sunday.

(35)

That is either the Sunday of the 51st, 52nd or 53rd week.

(36)

That is either the Sunday of the 51st, 52nd or 53rd week.

(37)

On MS-DOS, OS/2 and some other operating systems, the name of the standard resource file is `HOME/gcalrc' (without a leading `.').

(38)

On MS-DOS, OS/2 and some other operating systems, another character will be used, e.g. `;' on MS-DOS and OS/2.

(39)

Normally `HOME/share/gcal'.

(40)

Normally `/usr/local/share/gcal' or `$prefix/share/gcal'.

(41)

Operating systems like MS-DOS or OS/2 use the `\' (Backslash) character for separating a file directory from a file name.

(42)

For example Tab, Space, Form-feed and similar characters.

(43)

Normally, this is for example equivalent to a value of 32,767 == (2^15)-1 on a 16-Bit machine architecture; to a value of 2,147,483,648 == (2^31)-1 on a 32-Bit machine architecture etc.

(44)

Apart from the possibility, that a list of days can be used in such a case.

(45)

Implicit solution.

(46)

Or 366 in leap years.

(47)

Apart from the possibility, that a list or a range of days can be used in such a case.

(48)

Apart from the possibility, that a list of days can be used in such a case.

(49)

Like `%i', `$a'...

(50)

These are potentially non-printable.

(51)

That is the character with the value zero in the code table of the used character set.

(52)

These are internally skipped and remain undisplayed therefore.

(53)

Rational!

(54)

Physically and logically.

(55)

A mechanism similar the method which is used by the C Preprocessor.

(56)

Thus, a file name which is embraced by `""' or `<>'.

(57)

Even if operating systems like MS-DOS or OS/2 permits such a disk/drive specification on principle.

(58)

A path name lead by the user respectively system data file directory name.

(59)

The included file tries to include itself again.

(60)

The included file is included again by another file that occurs at a deeper place in such a chain.

(61)

Except the date variable e which is internally reserved for the Easter Sunday's date, so it cannot be assigned or operated therefore. And except the date variable t which is internally reserved for today's date, so it likewise cannot be assigned or operated.

(62)

Or the name of another date variable, which is already defined.

(63)

In the command line, environment variable GCAL or response file.

(64)

They are only done locally.

(65)

In the command line, environment variable GCAL or response file.

(66)

They are only done locally.

(67)

Two days before adaptation till two days after adaptation.

(68)

This is equivalent the `--shift=1' option.

(69)

Listed in decreasing priority as they are respected.

(70)

For example fr for French, es for Spanish....

(71)

Strictly speaking, an extended language code information.

(72)

Or other language codes, for which a message catalog will be created and distributed in future.

(73)

Or to be more precise, of the extended language code information en_US.

(74)

All other internal defaults of the simple en language code information just meet their criteria.

(75)

Normally, it only needs to match some part of the text in order to succeed.

(76)

A space is printable, but not visible, while an `a' is both.

(77)

Characters that are not control characters.

(78)

Characters that are not letter, digits, control characters, or space characters.

(79)

Such as Space, Tab, and Form-feed, to name a few.

(80)

That is the text part of a Gcal resource file line.

(81)

The same as a text part of a resource file line in Gcal.

(82)

The succeeding rules are analogously valid for the other permitted date formats.

(83)

RFC is the abbreviation of Request for Comments.

(84)

The course angle gives the direction, which is the vertex of a great circles arc (Orthodrome) that is casted between two points on a surface of a sphere, at a meridian (Gcal uses a geoid (rotation ellipsoid) that is calculated taking pattern from the World Geodetic System, short W.G.S, that was designed in 1961). Such an arc is the shortest geodetic connecting line between two points on a sphere. Indeed, the course angles on such an arc are changing continually, because the circular line that is casted intersects each meridian with another angle -- except the case, that both co-ordinates are referring to exactly the same meridian (longitude), or to exactly the same latitude.
