4 subroutines which do display-type things
5 and use the newt library to do them
6.
7
810/02
9- tell user not to bother mailing list unless snapshot
10
1107/09
12- finish() calls g_erase_tmpdir_and_scratchdir to erase
13 tmpdir and scratchdir at end
14
1506/25
16- tried to fix newtFinished() segfault
17
1804/13/2004
19- lots of char[]'s are now *char's
20
2110/09/2003
22- allow DVD option for text-mode which_backup_type() too
23

28- b5 now means dvd (was udev)
29
3009/16
31- echo fatal error to screen before exiting
32- working on fatal_error()
33- swapped g_blurb2 and g_blurb3 in a few places to fix a GUI problem;
34 it shouldn't have worked! :) I think there's a mem-leak somewhere
35
3609/13
37- changed some '\n' occurrences to '\r\n'
38
3909/09
40- fixed silly bug in log_to_screen()

49- fixed popup_changelist_*()
50
5104/27
52- replace newtFinished() and newtInit() with
53 newtSuspend() and newtResume()
54
5504/25
56- after comparing, popup the changelist for the user
57- moved the relevant code from compare_to_cds() into
58 compare_mode(), so that tape users may benefit too
59
6004/24
61- added lots of assert()'s and log_OS_error()'s
62- cleaned up a few uninitialized strings (valgrind)
63
6404/22
65- line 1181 - 'read from' (not 'restoring from')
66
6703/15/2003
68- fixed potentially infinite loop in log_to_screen (Tom Mortell)
69
7012/04/2002
71- changed "Pick file" to "Non-matching files"
72
7311/28
74- finish() now unregisters Mondo's pid
75
7610/28
77- unmount tmpfs if fatal_error
78
7910/04
80- more XMondo-related work
81- added some =NULL's in a few places
82
8309/01 - 09/30
84- write log_to_screen()'s string to stdout if in text mode
85- update_progress_form_FULL(), update_evalcall_form(),
86 popup_and_*(), ask_me_yes_or_no() now write
87 XMondo-friendly info to stdout if in text mode
88- if fatal error then popup and say what the fatal error is
89- run_program_and_log_output() now takes boolean operator to specify
90 whether it will log its activities in the event of _success_
91- added popup_changelist_from_file(char*source_file, char*topic, void*call_if_entry_selected(void*));
92
9308/07
94- added some functions to let user choose backup dev + format
95
9607/27
97- created
