// AUTHOR: Oleg Kalosha

|

|
|
// ORIGINAL DATE: 7-29-98
|
|
//
|
|
// NOTES:
|
|
// 1. Prior to 11/13/98, it wasis assumed that for a given DSC/TSM file, any other associated
|
|
// filenames (BES, HTI) would not change over time. This assumption is no longer good.
|
|
// It had the unfortunate consequence that if there was a typographical error in an LST
|
|
// file there was no way to fix it while the system was running.
|
|
// 2. While the Online Troubleshooter is running, it is possible to change the LST file in
|
|
// order to add new troubleshooter topics, but it is not possible to remove troubleshooter
|
|
// topics. Thus, even if a topic which was listed in the old LST file is missing from the
|
|
// new one, that is not a relevant difference.
|
|
// 3. Normal form of a line in this file: any of the following:
|
|
// MODEM.DSC MODEM.HTI
|
|
// MODEM.DSC MODEM.HTI MODEM.BES
|
|
// MODEM.DSC,MODEM.HTI,MODEM.BES
|
|
// MODEM.TSM,MODEM.HTI,MODEM.BES
|
|
// Commas and spaces are both valid separators.
|
|
// Order within a line is irrelevant, although for readability, it is best to put
|
|
// the DSC/TSM file first.
|
|
// Extensions are mandatory. The only way we know it's (say) a template file is
|
|
// the .HTI extension.
|
|
// DSC/TSM file is mandatory. The others are optional, although if the HTI file is missing,
|
|
// there had better be a HNetHTIOnline / HNetHTILocal property in this network.
|
|
// 4. If the same DSC/TSM file is listed more than once, the last appearance dominates the
|
|
// earlier appearances.
|
|
// 5. For multilingual, each language goes in a subdirectory under the resource directory.
|
|
// LST file needs to contain paths relative to the resource directory, such as:
|
|
// ES\MODEM.DSC ES\MODEM.HTI
|
|
// DE\MODEM.DSC DE\MODEM.HTI
|
|
// FR\MODEM.DSC FR\MODEM.HTI
