309 * The path will be appended to any existing LD_LIBRARY_PATH from the
310 * environment (see note in code below).
312 * DefaultLoadOrder=native,elfdll,so,builtin
313 * A comma seperated list of module-types to try to load in that specific
314 * order. The DefaultLoadOrder key is used as a fallback when a module is
315 * not specified explicitely. If the DefaultLoadOrder key is not found,
316 * then the order "dll,elfdll,so,bi" is used
317 * The possible module-types are:
318 * - native Native windows dll files
319 * - elfdll Dlls encapsulated in .so libraries
320 * - so Native .so libraries mapped to dlls
321 * - builtin Built-in modules
323 * Case is not important and only the first letter of each type is enough to
324 * identify the type n[ative], e[lfdll], s[o], b[uiltin]. Also whitespace is
329 * native,elfdll,so,builtin
335 * There are no explicit keys defined other than module/library names. A comma
336 * separated list of modules is followed by an assignment of the load-order
337 * for these specific modules. See above for possible types. You should not
338 * specify an extension.
340 * kernel32, gdi32, user32 = builtin
341 * kernel, gdi, user = builtin
342 * comdlg32 = elfdll, native, builtin
343 * commdlg = native, builtin
344 * version, ver = elfdll, native, builtin
350 * This is a simple pairing in the form 'name1 = name2'. It is supposed to
351 * identify the dlls that cannot live without eachother unless they are
352 * loaded in the same format. Examples are common dialogs and controls,
353 * shell, kernel, gdi, user, etc...
354 * The code will issue a warning if the loadorder of these pairs are different
355 * and might cause hard-to-find bugs due to incompatible pairs loaded at
356 * run-time. Note that this pairing gives *no* guarantee that the pairs
357 * actually get loaded as the same type, nor that the correct versions are
358 * loaded (might be implemented later). It merely notes obvious trouble.
