This is a tool for upgrading status-go to a given version in:
${VERSION_FILE}
Which is then used by Nix derivations to build status-go for the app.
If the given name matches both a branch and a tag the tag is used.
Usage:
${SCRIPT_FILE} {version}
Examples:
# Using branch name
${SCRIPT_FILE} feature-abc-xyz
# Using tag name
${SCRIPT_FILE} v2.1.1
# Using commit SHA1
${SCRIPT_FILE} 1a2b3c4d
# Using PR number
${SCRIPT_FILE} PR-2134
