Time	Narration
00:00	Welcome to this tutorial on how to write letters using latex
00:06	You can see three windows:
00:08	These correspond to the three distinct phases in typesetting through latex:
00:13	creation of source file, compilation to produce the pdf file and viewing it through a pdf reader.
00:22	I am using the free pdf reader “Skim” in Mac OSX because it automatically loads the latest pdf file after every compilation.
00:34	There are pdf browers in Linux and also in windows that have this capability.
00:42	Let us go through the source file and see what each command does.
00:47	The first line says that this belongs to letter document class.
00:54	12 point is the text size.
00:57	The first component of the letter is the ‘from address’. It appears between the braces here
01:07	The result of this is seen in the top right hand corner of the output file.
01:14	Two consecutive slashes start a new line.
01:19	If I remove the double slashes from here –
01:25	save, compile using pdflatex –
01:37	you can see that these two lines get merged in one line.
01:43	Previously with a double slash we asked latex to split the line.
01:49	Now these reverse slashes are no longer there, so latex does not know that it has to break the line there.
01:56	Let me put the slashes back.
02:04	Save, Compile.
02:08	It is to be understood, that after every change we need to save before compilation.
02:15	Let us see what happens when we give an empty address.
02:21	Let me just come here,
02:24	mark it,
02:27	go to the end of the line, delete it, save it, compile it.
02:37	You can see that the from address has disappeared from here.
02:44	Note that today’s date appears automatically in American style: month, date and then year.
02:54	This is obtained throught the command slash date slash today.
03:02	We can prevent the automatic appearance of the date with an empty list, as we do now.
03:12	Save.
03:17	Compile.
03:18	The date has gone.
03:20	Suppose that we want to put our own date, let us enter it with date first as follows.
03:30	9th July 2007, Save, Compile.
03:40	Got the date.
03:43	This is the date on which this tutorial was created the first time.
03:47	On compiling it, we see this Indian format appearing in the output file.
03:53	Let us put the address back.
04:02	And the document is back to the previous state by recompiling.
04:08	The signature commands argument appears at the bottom of the letter.
04:17	We begin the document and then the letter.
04:22	The ‘to address’ comes first. It appears in the top left hand corner of the output.
04:30	I have addressed this to Mr. N. K. Sinha.
04:34	The command ‘slash opening’ is used to address the recipient.
04:40	You may have already noticed that all latex commands begin with a reverse slash.
04:48	The text of the letter comes next.
04:53	One starts a new paragraph in latex through a blank line as we show now.
05:00	Let me come here. Right now this sentence starting at ‘we are’ is here.
05:07	Let’s open. Let's take this to the next line.
05:12	I have left a blank line. Let me save this.
05:17	Compile this.
05:19	You can see that this has gone to a new paragraph
05:25	With a new paragraph, the letter has gone to two pages.
05:29	Let us see if the font size is reduced to 10, we can bring the letter back to one page.
05:37	Let me do that now
05:42	Save.
05:48	Compile.
05:49	You can see that the whole letter has come to one page.
05:54	Let me put this back to 12 pt.
06:00	And let me also remove this paragraph bit.
06:06	And let me compile this.
06:12	Okay.
06:14	I now want to explain the itemize environment which is created with a pair of begin and end itemize commands.
06:29	Every piece of text that starts with a ‘slash item’ appears in a bulleted form.
06:37	Can I get numbers in the place of bullets here?
06:41	You just have to change the itemize into enumerate as I do now.
06:46	Let me just change this to enumerate.
06:53	Save it.
07:00	Of course! It is always a good idea to save as often as possible.
07:05	Let me compile this again.
07:09	You can see that the bullets have become numbers now.
07:15	In closing, I have included, ‘Yours sincerely’, which comes here.
07:22	We have already talked about the signature.
07:26	Finally, the command cc helps mark this letter to other recipients.
07:35	I end the letter with ‘end letter’ command and then the document is completed with the ‘end document’ command.
07:44	Feel free to modify the content and try them out.
07:48	Until you become confident, change only one thing at a time and make sure by immediate compilation that whatever you have done is correct.
07:58	Although I talked about the letter writing process in a Mac, the same source file will work in all Latex systems including those in Linux and Windows operation systems.
08:10	This brings us to the end of this tutorial.
08:13	Thanks for listening.
08:14	This is ---------------(your name) from ---------------------(Affiliation and name of the place) signing off. Good bye.
