| 32 | -- This package, together with its child package Fname.UF define the | |
| 33 | -- association between source file names and unit names as defined | |
| 34 | -- (see package Uname for definition of format of unit names). | |

| 40 | -- Note: this package spec does not depend on the Uname spec in the Ada | |
| 41 | -- sense, but the comments and description of the semantics do depend on | |
| 42 | -- the conventions established by Uname. | |

| 45 | -- File Name Conventions -- | |
| 46 | --------------------------- | |
| 47 | ||
| 48 | -- GNAT requires that there be a one to one correspondence between source | |
| 49 | -- file names (as used in the Osint package interface) and unit names as | |
| 50 | -- defined by the Uname package. This correspondence is defined by the | |
| 51 | -- two subprograms defined here in the Fname package. | |
| 52 | ||
| 53 | -- For full rules of file naming, see GNAT User's Guide. Note that the | |
| 54 | -- naming rules are affected by the presence of Source_File_Name pragmas | |
| 55 | -- that have been previously processed. | |
| 56 | ||
| 57 | -- Note that the file name does *not* include the directory name. The | |
| 58 | -- management of directories is provided by Osint, and full file names | |
| 59 | -- are used only for error message purposes within GNAT itself. | |
