16    
17     # This function generate linker scripts in /usr/lib for dynamic
18     # libs in /lib. This is to fix linking problems when you have
19     # the .so in /lib, and the .a in /usr/lib. What happens is that
20     # in some cases when linking dynamic, the .a in /usr/lib is used
21     # instead of the .so in /lib due to gcc/libtool tweaking ld's
22     # library search path. This cause many builds to fail.
23     # See bug #4411 for more info.
24     #
25     # To use, simply call:
26     #
27     # gen_usr_ldscript libfoo.so
28     #
29     # Note that you should in general use the unversioned name of
30     # the library, as ldconfig should usually update it correctly
31     # to point to the latest version of the library present.

62     # This function is for bulk patching, or in theory for just one
63     # or two patches.
64     #
65     # It should work with .bz2, .gz, .zip and plain text patches.
66     # Currently all patches should be the same format.
67     #
68     # You do not have to specify '-p' option to patch, as it will
69     # try with -p0 to -p5 until it succeed, or fail at -p5.
70     #
71     # Above EPATCH_* variables can be used to control various defaults,
72     # bug they should be left as is to ensure an ebuild can rely on
73     # them for.
74     #
75 azarah 1.3 # Patches are applied in current directory.
76     #
77     # Bulk Patches should preferibly have the form of:
78 azarah 1.2 #
79     # ??_${ARCH}_foo.${EPATCH_SUFFIX}
80     #
81     # For example:
82     #
83     # 01_all_misc-fix.patch.bz2
84     # 02_sparc_another-fix.patch.bz2
85     #
86     # This ensures that there are a set order, and you can have ARCH
87     # specific patches.
88     #
89 azarah 1.3 # If you however give an argument to epatch(), it will treat it as a
90     # single patch that need to be applied if its a file. If on the other
91     # hand its a directory, it will set EPATCH_SOURCE to this.
