The SAPO system history

SAPO is a set of powerful applications oriented towards the implementation of CARTA (process which make technical drawing from artistic creation), designs blond curtains, lace , etc. ... These products are manufactured in the German company Karl Mayer's textile machinery or also in acient looms leavers.
The SAPO system was originally created for HP's workstations with HP-UX operating system, because they were too much powerful than any PC on the market. The personal computimg progress make PC getting faster and cheaper, and became more interesting migrate the existing code to new and primitive Linux executed on personal computers.

We choose among all distributions of linux Redhat because was a free distribution and had a lot of similarities in the structure of directories and configuration files with the previous HP-UX.Redhat became a commercial product, so we looked for an open source alternative to maintain the same stability. The distribution chosen wasCentOS, which did not have the latest versions of software that other distributions derived from Redhat have like Fedora, but instead have a better stability .

With the idea of ​​avoiding the user to adapt to different environments that didn't have used, we kept the maximum appearance, for this reason, we install a CDE Linux compatible which had been used in the old HP-UX workstations, but now we are working to migrate the SAPO system to any modern desktops wich are integrated with current Linux versions like Gnome, or KDE, in order to improve the user experience and comfort as much as possible without lossing security and stability.

Notes of SAPO Desing system instalation

• Currently is needed to install SAPO on PCs and laptops and desktops where you can install a CentOS Linux operating system. The recommended version up to date is CentOS 5.x, because the old desktop CDE used with SAPO is incompatible with the latest version (CentOS 6 at the time of writing this manual).
• During installing an operating system, hard drive's data could be erased so you should backup your existing user data.
• The used editor for setup operations will be vi. This file editor is very powerful, but not recommended if you don't have previous experience. In this case, there are other editors more intuitive such as nano'.
• Remember that editing configuration files is a critical and extremely delicate operation and can cause the system will not boot properly.
• A new system installation have 4 stages:

1. Installing the Linux operating system 'CentOS 5.x'.

3. Installing the system design 'Frog'.
4. Installing additional applications.
