5 I am continuing to maintain the file command. I welcome your help,
6 but to make my life easier I'd like to request the following:
8 - Don't change the version numbers!
10 If your changes are extensive, I will have to work hard to
11 integrate them into my version. If you check it into SCCS locally,
12 the version numbers will likely be kept. IF you check it into RCS
13 or CVS locally, please use -k to keep the version numbers, and
14 please use branch deltas (1.21.1, 1.21.2, ...). If you don't do
15 this, I will likely be unable to use your changes; life's just too
18 - Do not distribute changed versions.
20 People trying to be helpful occasionally put up their hacked versions
21 of the file command for anonymous FTP, and people all over the
22 world get copies of the hacked versions. Within a day or two I am
23 getting email from around the world asking me why "my" file command
24 won't compile!!! Needless to say this detracts from the limited
25 time I have available to work on the actual software. Therefore I
26 ask you again to please NOT distribute your changed version. If
27 you need to make changes, please add a patch file next to the
28 distribution tar, and a README file that clearly explains what you
31 Thank you for your assistance and cooperation.
35 This is a rough idea of the control flow from the main program:
38 file.c process (called for each file)
41 fsmagic.c file_fsmagic()
42 (handles statbuf modes for DEV)
43 (handles statbuf modes for executable &c.
45 funcs.c: file_buffer()
46 compress.c file_zmagic()
47 is_tar.c file_is_tar()
48 softmagic.c file_softmagic()
49 match() - looks for match against main magic database
50 ascmagic.c file_ascmagic()
51 readelf.c file_tryelf()
