One reason is that we are not dependent on the software supplier for upgrades, and we can extend the software when needed. No one ‘owns’ the software, so we can plan for years ahead with confidence.

But it’s give and take. We freely distribute much of the programs we write inhouse. As other people use these, they debug them for us too, so it is a win–win situation.

Examples of free software we use are: TeX, XSLT, Python, Java, GNU/Linux, PHP, Apache, Perl, SVN, CVS, Postgres, MySQL, Mantis, GForge, Mailman, Emacs, Vim, and many more…

This has been brought about by redefining the margins and page height/width and related dimensions to fit into that of the computer screen. By changing the options to “print” you can switch the package to format the document in the conventional way as per the dictates of your class file.

  • to devise a method for easier technical presentation.
  • to help the mix of mathematical formulae with text and graphics which the present day WYSIWYG tools fail to accomplish.
  • to exploit the platform independence of TeX so that presentation documents become portable.
  • to offer the freedom and possibilities of using various backgrounds and other embellishments that a user can imagine to have in his presentation.

PDFdraftcopy makes use of alternate technique of keeping the text string as another layer by tweaking the output routines. Code from several packages have been blatantly stolen to do this job. PDFdraftcopy also supports inclusion of watermark which could be any graphic that would be accepted by pdfTeX.

As such, a package viz., PDFTricks.sty has been written to circumvent this limitation, so that the extensive facilities offered by the powerful PSTricks package can be made use of in a pdfTeX document. This is brought by making use of the shell escape function available in the web2c TeX compiler, while this package is of no use to other commercial implementations.

Itemized and enumerated lists can be typesetted within paragraphs, as paragraphs and in a compact version. Most environments have optional arguments to format the labels. Additionally, the LaTeX environments itemize and enumerate can be extended to use a similar optional argument.

The nomencl package should help authors format a nomenclature. It uses the powerful capabilities of the MakeIndex program to generate such a list automatically using information provided by the author throughout the text.

But it is difficult to find out an uncited bibliographic item in the body text while it is listed in the refrence list of your document. Bibcheck package helps you to find this out.

  • include a landscape table as a float.
  • format the caption exactly to the width of the table.
  • some other hooks that would add a little extra vertical space around horizontal rules in the tabular.
