The programming of this site is based on: Site Contents Manager  Site Contents Manager (SCM - web site managing software - SCM 3.1 ) belongs to Piet M. Hermans (PMH that’s me). SCM was inspired on the idea that being computers so versatile it should be possible to: Work on the aesthetic aspect only once for all pages Not need to write and rewrite links and then check everything again for broken ones Integrate new programmed modules in an easy manner. Manage multiple languages in a coherent way and that any site should have an easy to manage user interface, login, email check, newsletter, search function, and so on, not having to put together bits and pieces from here and there. So that is what SCM is about. Most of the code has been written by myself, and some pieces of code I have taken from open source freely available programs. The PHP Manual (available here) has been the fountain for scripting code.  I have also used some code and ideas found in PHP-Nuke (by Francisco Burzi) - and some found in an ASP system called Safeworx - So this is an acknowledgement to them. All of the scripting is done in PHP, the current release is  5.3.2  There are here and there some bits and pieces of javascript, I just can't recall where I got those from, but I can say for sure that I've seen similar stuff all over the web so let us just thank the Netscape folks for all of it. All Data base operations are based on MySQL, though SCM also supports a text based data access. This software has been tested on the Apache server under Linux and Windows, it must do fine on any system that supports PHP, in this particular case Apache.   Our Work Here - Nuestros Trabajos Aqui
