6 # @MAINTAINER:
7 # base-system@gentoo.org
8 # @BLURB: many extra (but common) functions that are used in ebuilds
9 # @DESCRIPTION:
10 # The eutils eclass contains a suite of functions that complement
11 # the ones that ebuild.sh already contain. The idea is that the functions
12 # are not required in all ebuilds but enough utilize them to have a common
13 # home rather than having multiple ebuilds implementing the same thing.
14 #
15 # Due to the nature of this eclass, some functions may have maintainers
16 # different from the overall eclass!

18 inherit multilib portability

27 # conjunction with the ebeep function. If the EPAUSE_IGNORE env var is set,
28 # don't wait at all.

37 # printing a message the user should probably be reading and often used in
38 # conjunction with the epause function. If the EBEEP_IGNORE env var is set,

83 # and not the full path ..

93 EPATCH_FORCE="no"
94
95 # This function is for bulk patching, or in theory for just one
96 # or two patches.
97 #
98 # It should work with .bz2, .gz, .zip and plain text patches.
99 # Currently all patches should be the same format.
100 #
101 # You do not have to specify '-p' option to patch, as it will
102 # try with -p0 to -p5 until it succeed, or fail at -p5.
103 #
104 # Above EPATCH_* variables can be used to control various defaults,
105 # bug they should be left as is to ensure an ebuild can rely on
106 # them for.
107 #
108 # Patches are applied in current directory.
109 #
110 # Bulk Patches should preferibly have the form of:
111 #
112 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
113 #
114 # For example:
115 #
116 # 01_all_misc-fix.patch.bz2
117 # 02_sparc_another-fix.patch.bz2
118 #
119 # This ensures that there are a set order, and you can have ARCH
120 # specific patches.
121 #
122 # If you however give an argument to epatch(), it will treat it as a
123 # single patch that need to be applied if its a file. If on the other
124 # hand its a directory, it will set EPATCH_SOURCE to this.

1114 # vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1115 # lseek(3, -4, SEEK_END) = 2981250
