174 // Since version 6.5.0 of SALOME, user file is situated in the ~/.config/salome

176 // version of application is searched, user home directory is also looked through,
177 // with lower priority.
179 // Since version 6.6.0 of SALOME, user file name on Linux is no more prefixed by dot
180 // symbol since it is situated in hidden ~/.config/salome directory. Files with dot
181 // prefix also though taken into account (with lower priority) for backward compatibility.
184 // - Currently the following format of version number is supported:
185 // <major>[.<minor>[.<release>[<type><dev>]]]
186 // Parts in square brackets are considered optional. Here:
187 // * major - major version id
188 // * minor - minor version id
189 // * release - maintenance version id

192 // * dev - dev version or patch number
193 // All numerical values must be of range [1-99].
