# Purpose {{{
## Create a temp file (to monitor) if an upgrade is available for Self Service Password (SSP)
## project on Github.
## It's based on .deb package installation to check the current version.
## It can also be based on installation from source if the self-service-password's
## root is given as first argument.
## How-to use {{{
### 1. Needs releasetags script, in the same directory
### cf. https://git.ipr.univ-rennes1.fr/cellinfo/scripts/src/master/github/releasetags
# wget https://git.ipr.univ-rennes1.fr/cellinfo/scripts/raw/master/github/releasetags
### 2. Create a cron job, eg:
#00 20 * * * root /opt/repos/ipr.scripts/github/check.self-service-password.update
### 2-1. Create a cron job with Self Service Password (SSP) directory as first argument, eg:
#00 20 * * * root /opt/repos/ipr.scripts/github/check.self-service-password.update /var/www/self-service-password
### 3. Monitor the temp file: /tmp/.github.self-service-password.upgrade
# Or enable MAILTO in cronjob and edit the script to print a message.
# Or send a mail.
# …
## }}}
