Change is a non-interactive text editor, similar to sed, but much easier to use. It works by substituting a specified target pattern in the source text with another specified text pattern. It can operate on multiple files specified on the command line, or it can operate upon stdin/stdout in filter mode.
SATFORM is a forms processor which provides a facility to print word processor-quality letters/reports by merging a data source with a template form. The output is suitable for HP LaserJet III (PCL) or later compatible printers. SATFORM uses an HTML-style markup system (SAT/ML) to define document template forms. It is also possible to make use of SAT/ML formatting to process embedded SAT/ML tags using the companion SATFILTER utility.
XMLDB uses an RDBMS to persist arbitrary XML documents. Due to its storage mechanism, searching for and recalling documents is extremely quick. You can also perform XSL translation on documents with surprising speed. The library can be used in any program to store libxml2 documents. A PHP module is also included, making XMLDB into a complete three-tier Web application development suite.
batemail is a Perl script that you slip between your MTA (e.g. Sendmail) and your local mailer (e.g. Procmail) to strip potentially nasty attachments from email messages. It takes input on STDIN, removes executable MIME attachments, and gives the result to the local mailer. The criteria for a taboo attachment are that the filename ends in one of several "blacklisted" extensions (EXE, VBS, etc.).
Pine Privacy Guard is a small Perl script used to interface Pine and GnuPG for the secure exchange of email. It allows Pine users to conveniently encrypt, decrypt, clear-sign, and verify clear-signed email. Other features include the secure storage of secret key passphrases during a session, alias support, simple installation, and compact, well-documented code.
Maildrop Spam Filter is a Maildrop script file for identifying and adding a header to possible spam. Using the header, suspected spam can be filed in a low-priority mail folder or trashed. All suspected spam is edited to change text/html MIME parts to text/plain so that HTML is not rendered if the message is viewed.
Apache SpamAssassin is an extensible email filter that is used to identify spam. Once identified, the mail can then be optionally tagged as spam for later filtering. It provides a command line tool to perform filtering, a client-server system to filter large volumes of mail, and Mail::SpamAssassin, a set of Perl modules allowing Apache SpamAssassin to be used in a wide variety of email systems.
ppmcaption adds text to PPM, PGM, or PBM images. Multiple blocks of text can be placed on the image, with varying fonts, font sizes, colors, transparency, and alignment. Any BDF font file can be used for the text. The advantage of using this program instead of a pipeline of PBM filters is that ppmcaption is much faster and easier to use.
