.SYNOPSIS
14 + 15 +
Build the SRT static libraries installer for Windows.
16 + 17 +
.PARAMETER Version
18 + 19 +
Use the specified string as version number from libsrt. By default, if
20 +
the current commit has a tag, use that tag (initial 'v' removed). Otherwise,
21 +
the defaut version is a detailed version number (most recent version, number
22 +
of commits since then, short commit SHA).
23 + 24 +
.PARAMETER NoPause
25 + 26 +
Do not wait for the user to press <enter> at end of execution. By default,
27 +
execute a "pause" instruction at the end of execution, which is useful
28 +
when the script was run from Windows Explorer.
