This gets us close to using the same modeline in all files we run through Asciidoc, as well as adding the spell and spelllang declarations, just as we had in NEWS already. The choice of 'en_us' is mainly for consistency and because the body of work already uses these spellings. Signed-off-by: Dan McGee <dan@archlinux.org>

vercmp - version comparsion utility
|

|
|
|
|
Synopsis
|
|
--------
|
|
'vercmp' <version1> <version2>
|
|
|
|
|
|
Description
|
|
-----------
|
|
'vercmp' is used to determine the relationship between two given version
|
|
numbers. It outputs values as follows:
|
|
|
|
* < 0 : if ver1 < ver2
|
|
* = 0 : if ver1 == ver2
|
|
* > 0 : if ver1 > ver2
|
|
|
|
Version comparsion operates as follows:
|
|
|
|
Alphanumeric:
|
|
1.0a < 1.0alpha < 1.0b < 1.0beta < 1.0p < 1.0pre < 1.0rc < 1.0
|
|
Numeric:
|
|
1 < 1.0 < 1.1 < 1.1.1 < 1.2 < 2.0 < 3.0.0
|
|
|
|
Additionally, version strings can have an 'epoch' value defined that will
|
|
overrule any version comparison (unless the epoch values are equal). This is
|
|
specified in an `epoch:version-rel` format. For example, `2:1.0-1` is always
|
|
greater than `1:3.6-1`.
