| 23 | |
| 24 This function compares strings S1 and S2: | |
| 25 1) By PREFIX in the same way as strcmp. | |
| 26 2) Then by VERSION (most similarly to version compare of Debian's dpkg). | |
| 27 Leading zeros in version numbers are ignored. | |
| 28 3) If both (PREFIX and VERSION) are equal, strcmp function is used for | |
| 29 comparison. So this function can return 0 if (and only if) strings S1 | |
| 30 and S2 are identical. | |
| 31 | |
| 32 It returns number >0 for S1 > S2, 0 for S1 == S2 and number <0 for S1 < S2. | |

| 34 This function compares strings, in a way that if VER1 and VER2 are version | |
