LibUCW
What's that?
- LibUCW is a general-purpose C library providing both implementation of common algorithms (like sorting, heaps), - support for performance computing (fast buffered IO) and some generic data structures. - In short, it is a library of things the authors consider useful in most of programs written in C. -
- As a bonus, there is a build system you can use in your program, documentation system and few perl modules. + The UCW library aims to provide a set general purpose tools for programming + in the C language. In other words, to make writing of complex and very efficient + programs in plain C a pleasure.
- It is developed as part of the Sherlock Holmes search engine. + It originated as a part of the Sherlock Holmes search engine, + but it is now developed separately. + However, the primary development motivation is still to serve the needs of projects demanding + both extreme speed and elegance.

Additional libraries
+Documentation
- The package contains few other libraries which you might find useful. - You can build & install libUCW with them or without. - However they are not documented and are more specific. -
-
-
- libcharset – allows manipulation with character sets. -
- libsh – the Sherlock Holmes library. It contains some routines for storing large amounts of data and alike. -
- liblang – guessing of text language. -
- libimages – manipulation with images. -

If you use the library to your pleasure, the authors will be glad to hear that at the same address.
Extra libraries
++ The package also contains several other libraries from the Sherlock Holmes project, which you might find useful. + So far, they are completely optional and not much documented. +
