18 | // Class for Parsing simple text configuration files // | |
19 | // It produces a TList for the TObjArrays with the name of the Key | |
20 | // the TObjArray contain the Values, split from kommas, as found in the // | |
21 | // Configutation file. // | |
22 | // // | |
23 | // The configuration file has a simple structure: // | |
24 | // * Lines starting with a # or empty lines are ignored // | |
25 | // * Key and Value are separated either by a <tab> or <space>es // | |
26 | // // | |
27 | // Currently the class is used in the TPC DAs to allow an adjustment of // | |
28 | // the most relevant parameters without recompiling the DAs // | |
