/********************************************************************
* Description: inivar.c
* prints to stdout the INI file result of a variable-in-section
* search, useful for scripts that want to pick things out of INI files.
*
* syntax: inivar -var <variable> {-sec <section>} {-ini <INI file>}
*
* Uses emc.ini as default. <variable> needs to be supplied. If <section>
* is omitted, first instance of <variable> will be looked for in any
* section. Otherwise only a match of the variable in <section> will
* be returned.
