`*  qseries package version 1.1 - Mon Jul 16 15:24:26 EDT 2012`
`*  This version tested on Maple 10, 11, 12, and 13`
`*`
`*`
`*  Changes since version 1.0`
`*`
`*      *  Added new function qdegree`
`*         qdegree(QS) returns degree in q.`
`*`
`*      *  Added new function findcong`
`          This function finds congruences c(A*n+B) == 0 mod C`
`          for a give qseries f=add(c(n)*q^n).`
`*`
`*      *  Added new function qs2jaccombo`
`          This function converts a sum of q-series to a sum`
`          of jacprods if possible. `
`*`
`*      *  Local vars added to procs where necessary`
`*`
`*      *  jacprodmake now takes 3 or 4 args`
`*         jacprodmake(f,q,T) works as before.`
`*         jacprodmake(f,q,T,P) returns a jacprod (if it exists) on`
`          base q^b where b is a divisor of P. ERROR is returned `
`          if f is not a jacprod.`
`          This new version also handles the case where the coeff `
`          of q^0 is not 1.`
`          PLEASE report any bugs.`
`*`
`*      *  New hidden function periodfind2 added. `
`          This is used by jacprodmake to find period assuming it`
`          is a divisor of a given integer.`
`*`
`*      *  New hidden function jacmake now takes 2 or 3 args.`
`*         It is used by jacprodmake.`
