At the begining of the 21st century, astronomical photometry has changed a lot. Instead of visual and photoelectric observation, the observers began to use CCD cameras. The CCD cameras became cheaper and therefore more affordable even for amateur astronomers. This gave rise to the demand for software tool for processing the CCD-data, which would be available for the amateur astronomer, user-friendly, but also using reliable algorithms.
In April 2003 the C-Munipack Project was started; its goal was to supply astronomers with powerful but also user-friendly tool for processing their CCD-data. At the time, two similar tools existed: MuniDOS, a text-mode program, which is somewhat limited by the user interface. Additionaly, according to the authors, the program is not using modern algorithms, and no future development is planned. The other available was Munipack, written partly in Fortran and partly in C. Munipack is modern and still maintained, but there were several disadvantages: the users of the Windows operating system would have severe problems with its compilation, and the graphical interface, that program offers, is available only for unix-based operating systems. Of course, there are some commercial products avaiable on the market, some of them are really good, but these products are not affordable for amateur astronomers, since they have to pay for everything by themselves.
I would like to thank to all my colleagues, who contributed with their ideas, advice, and suggestions, to this program. Namely to Filip Hroch for sharing the Munipack source code, and for helping with porting it from Fortran to C, to Lukas Kral for sharing his Varfind source code, to Miloslav Zejda, Ondrej Pejcha and Petr Svoboda for helping with testing and valuable suggestions to the user interface and to Jitka Kudrnacova and Petr Lutcha for help with english version of the documentation.
