9# @BLURB: functions which simplify manipulation of ${PV} and similar version strings
10# @DESCRIPTION:
7# This eclass provides functions which simplify manipulating $PV and similar 11# This eclass provides functions which simplify manipulating $PV and similar
8# variables. Most functions default to working with $PV, although other 12# variables. Most functions default to working with $PV, although other
9# values can be used. 13# values can be used.
10# 14# @EXAMPLE:
11# Simple Example 1: $PV is 1.2.3b, we want 1_2.3b: 15# Simple Example 1: $PV is 1.2.3b, we want 1_2.3b:
12# MY_PV=$(replace_version_separator 1 '_' ) 16# MY_PV=$(replace_version_separator 1 '_' )
13# 17#
14# Simple Example 2: $PV is 1.4.5, we want 1: 18# Simple Example 2: $PV is 1.4.5, we want 1:
