| 26 | -- This package keeps two mappings: from unit names to file names, | |

| 29 | -- This mapping is used to communicate between the builder (gnatmake or | |
| 30 | -- gprbuild) and the compiler. The format of this mapping file is the | |
| 31 | -- following: | |
| 32 | -- For each source file, there are three lines in the mapping file: | |
| 33 | -- Unit name with %b or %s added depending on whether it is a body or a spec | |
| 1d24fc5e | 34 | -- This line is omitted for file-based languages |
| 9763f8c8 AC |
35 | -- File name |
| 36 | -- Path name (set to '/' if the file should be ignored in fact, ie for | |
| 37 | -- a Locally_Removed_File in a project) | |
