DESCRIPTION

10       This module provides the following convenience functions:
11
12       path2mod
13           Convert file path to module name, e.g. File/Find.pm -> File::Find.
14
15       mod2path
16           Convert module name to file path, e.g. File::Find -> File/Find.pm.
17
18       path2dep
19           Convert file path to conventional dependency name, e.g.
20           File/Find.pm -> perl(File/Find.pm).  Note that this differs from
21           RedHat conventional form perl(File::Find).
22
23       mod2dep
24           Convert module name to conventional dependency name, e.g.
25           File::Find -> perl(File/Find.pm).  Note that this differs from
26           RedHat conventional form perl(File::Find).
27
28       verf
29           Format module version number, e.g. 2.12 -> 2.120.  Currently
30           truncated to 3 digits after decimal point, except for all zeroes,
31           e.g.  2.000 -> 2.0.
32
33           Update.  The algorithm has been amended in almost compatible way so
34           that versions do not lose precision when truncated.  Now we allow
35           one more .ddd series at the end, but .000 is still truncated by
36           default, e.g. 2.123 -> 2.123, 2.123456 -> 2.123.456.
37
38       verf_perl
39           Format Perl version number, e.g. 5.005_03 -> 1:5.5.30.
40
41       sv_version
42           Extract version number from B::SV object.  v-strings converted to
43           floats according to Perl rules, e.g. 1.2.3 -> 1.002003.
44
45       argv
46           Obtain a list of files passed on the command line.  When command
47           line is empty, obtain a list of files from standard input, one file
48           per line.  Die when file list is empty.  Check that each file
49           exists, or die otherwise.  Canonicalize each filename with
50           "File::Spec::rel2abs()" function (which makes no checks against the
51           filesystem).
52
53       inc Obtain a list of Perl library paths from @INC variable, except for
54           current directory.  The RPM_PERL_LIB_PATH environment variable, if
55           set, is treated as a list of paths, seprarated by colons; put these
56           paths in front of the list.  Canonicalize each path in the list.
57
58           Finally, the RPM_BUILD_ROOT environment variable, if set, is
59           treated as installation root directory; each element of the list is
60           then prefixed with canonicalized RPM_BUILD_ROOT path and new values
61           are put in front of the list.
62
63           After all, only existent directories are returned.
64
65       explode
66           Split given filename into its prefix (which is a valid Perl library
67           path, according to the inc() function above) and basename.  Return
68           empty list if filename does not match any prefix.
