Newfangle is a literate programming technique for LyX (or LaTeX) inspired by notangle. It comes in two parts. The weave part that produces the formatted document is implemented entirely in LaTeX, and the tangle that generates the source code is implemented in awk for portability. Naturally, newfangle is written using literate programming techniques, using itself, and so the source is also the documentation. The source is written using the LyX document editor, an excellent front end to LaTeX. LyX is not required, but newfangle provides formatting support for LyX. Literate programming makes you write good code, because if you can't write a good justification or explanation for your code, it makes you think again and write something that you can explain.
ofc2kmm is a script which converts bank statements from Banco do Brasil and Caixa Economica Federal in OFC format to a QIF format accepted by Kmymoney, a personal finance management software for Linux. It should be run directly from the Kmymoney QIF import feature, where you can specify external data converting scripts.
pwgrep is a simple password manager that manages a database file using encryption of GnuPG. It uses encryption and version control on all of the passwords that are stored. The password database can be used on several hosts at once with automatic synchronization. Even several users can share the same password database. The versioning system will keep track of who was changing which entries and at which time. The versioning system to use can be configured (and is Subversion by default). Besides passwords, pwgrep can also be used for storing a collection of files like certificates. The file shredding command for secure deleting of temporary files can be configured. A local backup of all database changes is automatically made. It can be used without a GUI (such as through an SSH session).
runawk is a small wrapper for the AWK interpreter that helps one write standalone AWK scripts. Its main feature is to provide a module/library system for AWK which is somewhat similar to Perl's "use" command. It also allows one to select a preferred AWK interpreter and to set up the environment for AWK scripts. Dozens of ready for use [modules].awk are also provided.
