# NAME
-# lf-activate-venv [-p|--python python] [--no-path]
+# lf-activate-venv [-p|--python python] [-v|--venv-file] [--no-path]
# [--system-site-packages] [package]...
#
# SYNOPSIS
# or
# lf-activate-venv lftools
# or
-# lf-activate-venv --python 3.6 git-review
+# lf-activate-venv --python python3.8 git-review
+#
+# lf-activate-venv --python python3.8 --venv-file /tmp/.myvenv git-review
#
# DESCRIPTION
# This function will create a new Python Virtual Environment (venv) and
# to the PATH.
#
# The 'lf_venv' variable will be set so you can directly execute commands
-# in the venv with: $lf_venv/bin/command. Beware that subsequent calls to
-# lf-activate-venv() will overwrite 'lf_venv'.
+# in the venv with: $lf_venv/bin/command. lf-activate-venv() will check for
+# existing file '/tmp/.os_lf_venv' and set 'lf_venv' if the file exists.
+#
+# The function provides a --venv-file path for saving the value of the 'lf_env'
+# that can re-used later. By default '/tmp/.os_lf_venv' venv file is created
+# when the --venv-file option is not specified.
+#
+# Subsequent calls to lf-activate-venv() will re-use the existing venv
+# throught and will NOT overwrite 'lf_venv', if the '/tmp/.os_lf_venv'
+# already exists.
+#
+# If a new venv is required delete the file '/tmp/.os_lf_venv' before
+# calling lf-activate-venv() will create a fresh venv.
#
# By default all packages are installed with '--upgrade-strategy eager'.
# The venv will always contain pip & virtualenv.
